摘要
掌握雷达导引头所探测到的由反射电磁波形成的视在目标与真实的物理目标的关系，对于评估雷达导引头的探测、跟踪精度具有十分重要的意义。文章对靶机的简化模型的视在目标进行了计算，揭示了视在目标的变化规律以及视在目标相对于真实物理目标的偏离程度，为进一步研究复杂目标提供了思路。
In order to evaluate the detecting and tracking accuracy of the radar seeker, it is important to know the relation between the visual target which the radar seeker discovered and the real target. In this paper, the visual target of the predigestion model of target drone is calculated. The movinglaw of the visual target and the departure of the visual target from the real target is found out. The result is valuable for the study on the complex target.
