In electronic warfare, modern pulse compressed radar makes the simple deception jamming useless because of its complicated in-pulse modulation technology.
在电子战中，现代脉冲压缩雷达采用复杂的脉内调制技术，使简单的欺骗干扰难以奏效。

The signal modulation of velocity deception jamming is complex, and it is hard to complement anti jamming using the statistical feature extraction method.
速度欺骗干扰因信号调制较为复杂，难以用统计特征提取方法来实现抗干扰。
3
Due to additive relative motion between ground jamming emitters and SAR, the spurious phase modulation of transmission signal is produced.
