摘　　要：雷达侦察设备受同阵地强雷达信号干扰会产生许多虚假信号,采用匿影的方式可以对强信号进行有效抑制。为保证信号的截获概率和信号完整性,可以通过对全脉冲打匿影标记的方式并经过信号处理来去除虚假信号。实验证明,通过过滤特定标记的全脉冲在滤除虚假信号的同时,还能最大程度的保留真实信号的原始结构。In the condition of radar reconnaissance equipment generating many false signals due to strong radar signals in the same position,the strong signal could be suppressed with the method of blanking effectively. To ensure the interception probability and the integrity of the signal,a stamp is applied to all pulses to remove the spurious signal by signal processing. The results indicate that removing the stamped signals can retain the original structure of the real signals when filtering the false signals.
