相位天线偏置(DPCA)技术在雷达领域是一种经典的杂波抑制算法,该算法简单易行,有很高的实用价值。文中研究了数据域DPCA技术在机载双通道SAR地面动目标检测领域的应用,推导出点目标回波模型;介绍了时间域和多普勒域算法的原理;对多普勒域DPCA算法的工程化进行了研究;最后给出了模拟数据的仿真结果。

As one of the classical algorithms for clutter suppression in radar field,Displaced Phase Center Antenna(DPCA) Processing can be implemented easily and simply.In this paper,two kinds of raw data range DPCA algorithms-time range DPCA and Doppler range DPCA to use in bi-channel SAR/GMTI system are studied.The model of point target return is derived;principles of two methods are introduced;the applications of Doppler range DPCA technique is studied and the corresponding results of simulated based on the simulated data are put forward.
