An Algorithm of Matched Filter Based on Sub-band Processing in Integrated Receiver

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,针对雷达与雷达对抗侦察一体化接收结构,提出了一种基于子带处理的匹配滤波算法。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,能够实现宽带雷达与雷达对抗侦察一体化接收。通过理论分析和仿真实验验证了该算法的有效性。

An algorithm of matched filter to radar echo based on sub-band processing in receiving structure integrated radar and radar countermeasure reconnaissance is proposed. In this algorithm sub-band matched filter coefficients can be formed when transmitter waveform passed analyse filter banks. The problem of radar bandwidth wider than sub-band of receiver integrated radar and radar countermeasure re- connaissance can be resolved as matched filter to radar echo by sub-band processing. The receiver tech- nology 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.
