瞄准点漂动系指在跟踪寻的器接近目标飞行时微波辐射计视在回波源无法估计的横向突然移动现象。飞行试验记录表明,这种现象完全可以解释为观察时回波强度的一种突然变化,正像大家所知道的,这种变化是由复杂目标反射的辐射计回波的低阶干扰引起的,回波强度漂移假设是由坦克、卡车及其它目标的平面与角形部位之间的低阶干扰产生的,终端寻的过程中出现瞄准点漂动,首先需要跟踪器做某种相对横向运动,这种运动的产生或由于空气动力振动或由于有意改变接近的飞行路径。
Aiming Point Drift refers to the sudden abrupt movement of a microwave radiometer as the echo source can not be estimated when the tracking finder approaches the target flight. Flight test records show that this phenomenon can be completely interpreted as a sudden change in echo intensity observed, as we all know, this change is caused by the low-order interference of complex target reflection radiometer echo, The echo strength drift assumption is caused by the low-order interference between the plane and the angular parts of tanks, trucks, and other targets. Aiming point drift occurs during the terminal search. First, the tracer is required to do some relative lateral movement, which The generation of a movement or due to aerodynamic vibrations or due to intentional changes in approach flight path.
