Interference bias is an effective means to counteract the attack of precision-guided weapons. The key to the precision threat of precision-guided weapons is to be able to directly attack the key points. The premise of high-precision strike is that the missile-borne guidance mechanism must accurately lock the target and receive guidance correction signals in real time If the guidance signal is suppressed or interfered with, or the correction information is inaccurate, the guided weapon will not be able to accurately hit the target, which will greatly reduce its power. If the traditional camouflage protection technology uses "easy tolerance" to hide the target and interfere with the biased protection technology It is to put an "frosted mirror" on the incoming missile so that it cannot be seen clearly, and the sighting is not accurate, so that the guidance mechanism deviates from the target in the wrong direction, and this technology is more protective of important position targets that cannot be turned underground. Practical value. According to this text, "disturbance bias" can be most accurately summarized as? ['"Smoke bomb" camouflage protection technology.', '"Tracker" for Missile Guidance Signals.', '"Mishun San" of precision guided weapons.', '"Umbrella" for ground targets.']
