摘要
对二相编码信号的多普勒特性进行了研究,并给出了相应的多普勒补偿算法。运动目标回波信号的码宽变化可以忽略不计,而信号的整体多普勒频移则严重影响了接收机中滤波器的匹配特性。基于MTD的多普勒补偿算法能有效地矫正失配问题,从而可以有效地检测出运动目标。
The Doppler characteristics for Biphase Coded Signal and a compensation method are studied in this paper. The change of code wide can be ignored, while the Doppler frequency shift leads to the Doppler-mismatch in the Radar receiver severely. A compensation method based MTD is presented to correct the mismatch and detect the moving target effectively.
