监视雷达波束在遇到低空的反射体时，会因反射体的作用而发生反射现象，从而影响对目标位置的判断。重点讨论针对地面或低空反射目标造成的Ghost虚假目标的处理，首先分析和模拟了出现Ghost虚假目标的情况，而后研究针对这种情况的处理算法，充分考虑Ghost目标的形成原因，设计了一种软件处理算法，通过仿真，验证了该算法可以有效地减少Ghost虚假目标的出现，避免对管制人员造成不必要的干扰。

The radar could not detect the targets correctly when its beam hits some low altitude reflectors. In this paper we study mainly the ghost type false targets and its processing. In a few references researchers only describe this phenomenon and could not find a useful processing method. We can not obtain raw data for this situation to test our processing algorithm, and so in the first part, we simulate those data according to its cause of appearing. In the second part we suggest a processing method, which can reduce the appearance of Ghosts and avoid the interference to air controller.
