| Abstract: | An algorithm of matched filter to radar echo based on sub-band processing in receiving struc-ture 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 com-puter simulation have illustrated the validity of this matched filter algorithm based on sub-band processing. |
