摘　　要：本文基于高频地波雷达的实现原理,和目标角闪烁的基本原理,对雷达回波信号采用虚拟跳频的处理方式来抑制目标角闪烁.由模拟和实测数据实验证明,该处理方式既不影响点目标的回波信息,又对复杂散射目标有明显的角闪烁抑制,并且该处理方式的计算量开销小,完全可以用于实际工程.Based on the principle of high frequency ground wave radar in realization and the basic principle of the target＇ s angular glint, the target＇s angular glint in the echo signals of radar are suppressed by dummy frequency agility. Experiments show that the method can suppress the angular glint of the complex backward scatter target effectively without affecting the echo signals of the point target. Moreover, the method can be put into use in practical projects for its low computation cost .
