密集假目标干扰的峰均比改善方法

Improvement Method of PAPR of Dense False Targets Jamming

密集假目标干扰是一种对现代雷达有效的干扰模式。分析了密集假目标干扰信号产生中归一化存在的问题,找到了该问题的原因———干扰信号峰均比过大,提出了随机相位、多相序列、信号重构方法降低干扰信号的峰均比,通过仿真验证了方法的有效性,并对其存在局限性作了分析。

The dense false target jamming is an effective jamming mode to modern radars. This paper analyzes the existing problem of normalization in generating the dense false target jamming signals, and finds the reason that the peak-to-average power ratio （PAPR） of the jamming signal is too large, brings forward the methods of random phase, polyphase sequences and signal reconstruction to reduce PAPR,validates the validity of the methods through simulation,and analyzes its limitation.
