一种弹载SAR相位域调制欺骗干扰方法
|
摘要
从相位域假目标调制的角度提出了一种针对弹载合成孔径雷达的欺骗干扰信号产生方法。首先,干扰机根据侦察系统提供的弹载合成孔径雷达平台参数,将假目标模板按散射单元划分距离向单元,计算距离向单元内各散射单元对应的多普勒频率、多普勒频率的和函数、相位及幅度信息;其次,对截获的弹载合成孔径雷达信号按距离单元进行相位延时调整、假目标相位调制;然后,利用假目标模板获取的多普勒信号幅度信息进行雷达散射截面重建;最后,对各距离单元干扰信号求和后转发。仿真结果表明:由该方法产生的干扰信号能够形成期望的假目标,是一种有效的干扰方法。
A false target deceptive jamming signal generation method for countering missile-borne systsetic aperture radar( SAR) is proposed in this paper,which is based on phase domain false target template modulation. According to the parameters of missile-borne SAR detected by the reconnaissance system,the false target template is divided into scatter units by the jammer,the Doppler frequency of every scatter unit in the range bin,and the sum,phase and amplitude of the entire Doppler frequency are calculated. Then,the phase delay and modulation of the false target for the intercepted missile-borne SAR signal are made. Third,the amplitude extracted from the summed Doppler frequency of the range bin is used to rebuild the radar cross section of the false target template. Finally,jamming signals of the entire range bins are summed and retransmitted. Simulation indicated that the jamming signal generated by the proposed method in this paper could produce a false target in the missile-borne SAR image,proving this method to be effective one.
