Although subject to current technical means, the positioning accuracy provided by these two devices is far from satisfactory. They can only provide a rough orientation. The positioning error of ground radio stations is about one kilometer. In a world where the enemy and ourselves are intertwined, The zone is simply unusable.
Because of that, even if there is a special contact signal, it is still impossible to accurately distinguish the location of enemy and friendly radio stations within one kilometer. Therefore, this aircraft was transferred to the sky above the Aruhorqin Banner by the Anti-Japanese Federation, specifically in accordance with the predetermined plan. Guide the bomber group in the night bombing of the 7th Division.
Moreover, limited by the strength of the received signal, these two aircraft can only monitor the signals of radio stations with a power of more than fifteen watts, and cannot detect the five-watt radio stations commonly used by the Japanese brigade. However, this is a disguised solution. Interference may occur due to too many low-power radio stations, especially on the battlefield of Alukorqin Banner. This accuracy is enough.
After all, even on the ground, the monitoring accuracy and positioning of radio signals cannot reach 100 meters. Even on the ground, the radio direction finder and locator are specially used to crack underground radio stations and intercept ground signals. An accuracy of 500 meters can be said to be quite rare.
What's more, these devices are aerial radio signal receivers, direction finders, and locators used for bombing industrial bases and large cities. They can only provide a rough range. Although some improvements have been made under Yang Zhen's suggestions, However, it is still limited by the overall technology and cannot provide too high accuracy when positioning.
However, Professor Shu Xingbei, together with several of his students and colleagues, has come up with a complete set of improvement plans based on the ideas provided by Yang Zhen. After this battle, not only will the imitation of this equipment be fully started, Moreover, the improved positioning accuracy of radio signals intercepted on the ground can be roughly increased to about 500 meters. If it can be achieved, then this accuracy can be said to be almost equivalent to precision guidance at the moment.
Nowadays, after decades of advanced electronic technology, signals from electronic equipment can be locked through satellites. Airborne early warning aircraft and dedicated electronic intelligence reconnaissance aircraft can all accurately locate signals sent by ground equipment, not to mention with an accuracy of dozens of dozens. Meters, even if the accuracy is a few meters, it is considered a backward product. The most advanced products can even be positioned with an accuracy of tens of centimeters.
Advanced military reconnaissance satellites can clearly see car brands on the ground not only during the day, but also at night. Various airborne radars, advanced infrared equipment and thermal imaging cameras mounted on aircraft can accurately detect vehicle signs at night when there are no stars. Find the target and lock it.
Once a ground target is locked under such circumstances, coupled with various precision-guided bombs and missiles, there is almost no possibility of survival. Even a signal from a palm-sized mobile phone can be used as a strike means of precise positioning of targets.
But at the moment, the improvement of positioning accuracy still needs a little bit of exploration, especially since the foundation of the Anti-Japanese Alliance is extremely weak. There are many things that need to be explored for a long time. Yang Zhen can only provide advanced concepts, and talk about real theories. , his gadget can't even touch the door, it's only half a window at most.
Fortunately, the advanced concepts he proposed can provide a window for those researchers. Although there is a window grille, there is still half a window that can be used. For those true scientific leaders, with this half window, It is enough to lead them into a brand new palace.
Moreover, inaccurate accuracy is not only due to the technical capabilities of the equipment, which affects the accuracy of positioning, but is also subject to the training level of personnel and the inherent deviations that occur in manual work situations, which will also affect the accuracy of monitoring, especially on the battlefield. , when dealing with various radio signals coming from all directions, confusion is more likely to occur.
Even when these two aircraft were tested, they received signals from radio stations in six regions on six frequency bands. Everyone on the aircraft listened to the Japanese radio station boasting for half an hour in the cabin. Their so-called military prowess is also reflected in the broadcasts broadcast by the Puppet Manchukuo Radio and the Wang Puppet Radio to boast about the so-called friendly countries.
This is still a time when the electromagnetic environment is far better than that of later generations. If there were taxis on the streets in later generations, walkie-talkies used by various commercial, civilian, and military police, plus large and small radio stations and mobile phone signals, It is estimated that these people must be tortured to the point of going crazy.
Although those selected to serve as these staff members are all carefully selected from among the college students who came to the Northeast from Guanhai and have been strictly reviewed, as long as people are doing this kind of thing, they will never make any mistakes. It turns out that it is already good to be able to intercept signals on the ground with an accuracy of one kilometer.
This standard can even be said to have surpassed the level of the United States and the United Kingdom, which currently have the most advanced electronic technology. The British have already begun bombing Germany, but they are still far from this accuracy. As for their opponents, the Japanese, they have been left behind. I don't know how far it is out.
However, for the Anti-Japanese Alliance, they will not put all their hopes on these two radio signal positioning aircraft. In fact, including the 26th Regiment, all participating regiments of the 7th Division marched in two sequences. On both sides, a large number of ground bombing instructors and artillery observers were deployed.
However, these ground guides, who are coordinated by aircraft in the sky, do not need to be close to the reconnaissance like ordinary ground guides. In addition to constantly observing the Japanese army's route and adjusting the direction, all they need to do is to carry a A fifteen-watt radio station formed a cross signal source on both sides of the Japanese army's marching sequence.
Just place the intersection of the signal sources of the two radios at the head of your own marching sequence to observe the target, so that the British-made navigation system on the reconnaissance aircraft in the sky can receive the signals they send and determine your target. location.
The search troops sent by various departments of the Japanese army just followed common sense and circled around 800 meters away from them. Although the search was carried out extremely carefully, how could they find these ground guides one kilometer away, let alone these ground guides? , they undergo special concealment training before being put on the battlefield.
The radio antennas required for guidance are also hidden by trees. Except for specially trained military dogs, ordinary people, including Japanese soldiers, cannot detect them as long as they don't step on them. They are also not used for ground guidance. Visible light sources such as flashlights and signal lights only require a fifteen-watt wireless radio.
As for those who really need to do close reconnaissance, there are also professional scouts from the reconnaissance brigades directly under the military region to do it, and there is no need for them at all. Therefore, although these ground guides have a certain degree of danger, in general, as long as they are not unlucky enough to be killed by themselves If a human bomb explodes, the risk is still very low.
Although the Japanese army continues to advance, long before this battle, aviation and artillery had joined forces to complete the mapping of targets in Aruhorqin Banner, including the entire Western Manchuria battlefield, and marked it as an aviation map, and implemented a grid , each small box is marked and numbered accordingly.
In each small grid, there are relatively fixed ground guides and artillery correction personnel. Their task is only to monitor their own target areas. This combat mode was invented by Aviation Commander Fang Ziyi. In this way, although The manpower required was greater, but the bombing accuracy at night was much higher.
They did not need to move at all, they only needed to ensure that the radio signals within the area they were responsible for could be sent out smoothly and continuously. Before the Japanese army launched a comprehensive counterattack, the Anti-Alliance adopted a variety of methods, especially to ensure the accuracy of night bombing. In terms of this, it can be said that they have racked their brains and tried all kinds of methods and means.
Not only were ground bombing guides set up in the air and on the ground, but also high-power radio stations were established in Linxi, West Ujimqin Banner, Qiqihar, Jiangjun Temple, and the westernmost part of Aruhorqin Banner in the last time before the war. The system network of our own battlefield navigation and the signals sent back by the ground guides can not only be received by aircraft in the air.
The navigation network established on the ground can still be received if the transmitter adopts a ground wire and lengthens the communication antenna. Through various support methods adopted by the aviation force, although the accuracy of nighttime bombing is not as good as that of daytime bombing, the proportion has dropped. It's not very big.
As for the large-scale bombing at night, the bombers that had just completed night flight training had problems with their own navigation from the airport to the battlefield and problems with their formation in the air. They did not yet have the resistance of the Identifier Friend or Foe. Although the method to solve the problem was clumsy. A little bit different, but the method is simpler.
In order to ensure the safety of the air formation and prevent it from flying in the wrong direction in the vast night, in addition to the navigation function of the radio reconnaissance aircraft in the sky, there is also a strict rule in combat that when the aircraft takes off, cars are used as Directional instructions.
When the plane took off, the two cars turned on their lights crosswise outside the airport. The intersection of the lights pointed in the direction where the aircraft needed to be dispatched. At the same time, the intersection of the lights was also the gathering point for the bombers. All of them. Planes must gather in formation above this point. In the dark, as long as you pay a little attention, this point is relatively easy to spot. As long as you don't fly to the highest altitude that the plane can fly, there is absolutely no problem.
As for the air crews at various airports, after the ground personnel received the intelligence and found the location to be bombed according to the corresponding number on the map, they immediately calculated the combat distance. The aircraft participating in the battle maintained a fixed formation in accordance with the strict regulations of the aviation force. Speed, led by an aircraft equipped with signal receiving equipment, flew to the battlefield.
This speed is also mandated not to exceed 350 kilometers per hour. As long as the aircraft maintains this speed, there will basically be no clearing up of laggards. At the same time, when returning, the guidance aircraft is also equipped with flares. At the same time, several The fuselage of the guidance aircraft and the leader aircraft are also equipped with specially improved low-power searchlights.
When returning home, all the searchlights on these aircraft are turned on to maximum power to ensure that pilots who are not particularly skilled in instrument flying are guided to keep up with the flying team and not fall behind. The order of bombing is also after the lead aircraft enters, and the remaining aircraft Follow up later.
The time for all aircraft to drop bombs is strictly limited to a certain specified time. All aircraft, regardless of whether the bombs they carry are dropped cleanly, must return home after receiving the signal from the lead aircraft's signal flare. In addition, all aircraft participating in the battle must Equipped with a complete radio communication system.
At the same time, all bombers participating in night bombings were selected pilots who had completed instrument flight training. Therefore, the night bombings of the Anti-Japanese Alliance basically did not cause major problems. This night battle also allowed all participating pilots to accumulate experience. Rich experience in night bombing.
