研究了雷达与雷达对抗侦察一体化接收中的雷达回波接收问题,针对基于动态非均匀滤波器组的雷达与雷达对抗 侦察一体化接收结构,提出了一种宽带雷达回波相关接收的子带处理结构。该算法将雷达发射信号波形通过分析滤波器 组得到相应的子带匹配滤波器系数,实现了雷达回波匹配滤波的子带处理,解决了雷达带宽大于子带带宽时雷达回波匹 配滤波的问题。从而使得雷达带宽不受一体化接收中子带频率宽度的影响,能够有效实现宽带雷达与雷达对抗侦察一体 化接收。理论分析和仿真实验验证了该结构的有效性。

Wideband radar echo receiving issues in integrated receiving structure of radar and radar countermeasure reconnaissance system based on dynamic nonuniform filter banks is studied , on the basis of which, a sub-band processing structure for coherent receiving of wideband radar echo is put forward. In this algorithm sub-band matched filter coefficients can be formed when transmitter waveform passes analyse filter banks. The problem of radar bandwidth wider than sub-band of receiver integrated radar and radar countermeasure reconnaissance can be resolved as matched filter to radar echo by sub-band processing. The receiver technology integrated wideband radar and radar countermeasure reconnaissance can be realized because the bandwidth of radar is not decided by sub-band width of integrated receiver. Theoretical analysis and computer simulation have illustrated the validity of this matched filter algorithm based on sub-band processing.
