基于认知雷达的抗速度欺骗波形设计方法

A waveform design approach against velocity deception based on cognitive radar

根据认知雷达获得的目标和干扰速度信息,可自适应地设计初相扰动的线性调频(LFM)波形,使干扰能量经多普勒处理后避开真实目标多普勒谱附近区域,从而实现强速度欺骗干扰的有效抑制,以便对目标速度的检测。通过仿真分析,验证设计的波形能有效抑制速度欺骗干扰。

According to the target and jamming velocity information obtained by cognitive radar,the LFM waveform of initial phase disturbance can be designed adaptively,so that the jamming energy can be processed by Doppler to avoid the area near the Doppler spectrum of real target,in order to achieve the effective suppression of the strong speech deception and detect the target speed.Through the simulation analysis,it is verified that the proposed waveform can effectively suppress the velocity deception jamming.
