　(how long ago: novelist, military commentator, former cadre self-defense officer) Russia's invasion of Ukraine is a worrying situation that could happen now. If the invasion begins, both Russia and Ukraine will use drones (hereinafter referred to as "UAV"), and the most eye-catching drones will be the Bayer TB2 imported by Ukraine from Turkey. [photo] the drone "bilingual TB2". Ukraine is in the process of introducing 12 aircraft. Bayer TB2 was used by Azerbaijan in the Nagorno-Karabakh conflict in 2020, and its results were disseminated into images, making the world widely aware of the usefulness of drones. I think Ukraine has introduced 12 Baraktar TB2, and as during the Nagorno-Karabakh conflict, many people expect them to effectively attack the invading Russian army (you also expect that image to spread). On the other hand, some people claim that "Bayer TB2 will not work against Russian regular army opponents." These claims are based on the facts of the Nagorno-Karabakh conflict and the fact that Bayer TB2 was shot down in Syria and Libya. In this article, I will explain the background to this fact and verify whether Bayer TB2 can work in the event of a Russian invasion. Will Bayer TB2 be shot down? There is also a lot of information about the shooting down of Bayraktal TB2, but this is not based on this information, but through various means of interception to explore the possibility of shooting down, while conducting some technical discussions.

　[radar, can it be found in IRST] in order to shoot down a flying creature TB2, it must be found first. Radar is the main means of modern aerial search, but some people seem to think that Bayer TB2 can't be detected on radar. One of the reasons is that because the fuselage is small, there is less radar reflection. The professional performance is "RCS (Radar cross-section) is small". However, although the body is small, it is not really an invisible design of the body. If the formal stealth design is carried out, it is disadvantageous in aerodynamics, so it can be considered that the double star TB2 attaches great importance to the hysteresis performance for a long time and will not be invisible. Although there is no public Bayer TB2 RCS, it should be a much larger RCS than the real stealth aircraft known as birds and insects. Since the Showa era, the self-Defense Forces have been using drones as various training targets. These are smaller than binary TB2 and almost as big as missiles, but they are well reflected on radar. It is precisely because it is a reflection that it can be used as a target for training. However, during training, in order to adjust the RCS to the desired goal, something called a reflector is often installed to adjust the RCS. There is another reason for those who think that "Bayer TB2 cannot be picked up by radar". That is, the Bayer TB2 is low-speed. Modern radar enhances target capture by observing the frequency (wavelength) shift of radio waves and reflected waves emitted towards the target. This is a signal processing called MTI (moving-target indicator) processing. In the environment of electronic warfare with high electromagnetic noise, it is used to reliably capture the target in the environment with more reflected waves other than the target known as clutter. This is the signal processing in which the frequency of the reflected wave rises when the target is close and the Doppler displacement of the frequency decreases when it is far away, which is one of the gate processing. Because this is door processing, in the case of playing on the door, that is, in this case, the signal in which no Doppler shift occurs is eliminated as noise. As a result, goals that are not close and far away will disappear.
