瞄准点漂移是跟踪寻的头在飞行期间微波辐射计回波视在中心在横向方向上的一种急速的并且不可予料的偏移现象。这种现象可以从飞行试验记录中看出来,试验记录能园满地解释回波强度急速变化这一观测结果,这一点,众所周知是由于来自复杂目标的辐射计回波的低阶干涉引起的。回波强度偏移的起因是诸如坦克、卡车及其它目标的平面和角形体特征之间的低阶干涉现象。在末寻的期间,由于空气动力振动或者接近航线的控制,瞄准点漂移首先要求跟踪器有一定的相对侧向运动。 The aiming point drift is a fast and inadvertent shift in the transverse direction of the microwave sighting center of the microwave radiometer during the flight of the tracking head. This phenomenon can be seen from the flight test record, which is well-known due to the low-order interference of the radiometer echo from complex targets. The cause of the echo intensity offset is the low order interference phenomena between planar and angular body features such as tanks, trucks, and other targets. During the final search, due to aerodynamic vibration or approach control, aiming point drift first requires a certain relative lateral movement of the tracker.
