摘要
本文叙述了一种用于干扰线性调频连续波压缩雷达的基于宽带中频带通采样软件无线电结构的电子侦察干扰机。这种干扰机在数字信号处理器中对雷达信号进行短时傅里叶变换,测量雷达信号参数,然后根据干扰策略———距离波门拖引干扰,控制DDS产生干扰信号。最后利用Matlab进行仿真实验,证明这种方法能够有效干扰线性调频连续波压缩雷达。
The electronic reconnaissance jammer based on broad band intermediate frequency software radio architecture is given. DSP of this jammer takes STFT of radar signal and gets the signal parameter. According to RGPO , it controls DDS to produce jamming signal. Simulation results show that this method is good for jamming the chirp compression radar.
