LS-Relax算法抗诱饵诱偏

目标与有源诱饵常处于弹载雷达的同一分辨单元，致使导弹的命中概率大大降低。采用IS-Relax算法在多普勒域、角度域和复幅度域上实现了目标信号参数测量和目标检测，并应用于抗诱饵诱偏中以提高导弹的命中概率。此算法能有效地分辨出同一分辨单元内的多目标，精确地测量出各目标的多普勒频率、角度、幅度和初始相位等信息，以重构出目标或诱饵信号从而达到抑制诱饵诱偏干扰的目的。仿真结果表明，当SNR〉15dB，目标测角误差小于0．10，失调系数小于0．1。由此表明，算法的收敛性较好。

Anti-Decoy Using LS-Relax Algorithm

It is a serious problem for the missile-borne radar when targets and active decoys are in the same range-angle resolution cell,which can greatly reduce the fighting efficiency of the missile.The LS-Relax algorithm is utilized, which is achieved to measure parameters and detection on the joint fields of the Doppler-frequency,angle and complex amplitude.Some researches are done on anti-decoy to increase the fighting efficiency.Those parameters,including Doppler-frequencies,angles,amplitudes and phases,are mea...
