介绍了基于相位中心偏置天线(Displaced Phase Center Antenna，DPCA)的机载战场侦察雷达主杂波的抑制系统的设计与实现。该系统具有一定空-时二维处理能力，是空-时自适应处理(Space-Time Adaptive Processing，STAP)的一种简易工程实现。其对地杂波的抑制能力优于AMTI，特别是在动目标速度较慢时，优越性更为明显。通过对回波仿真数据的实际处理，证明了该系统工作的有效性。

This paper describes the design and implementation of an airborne radar ground clutter suppression system based on DPCA(displaced phase center antenna).This system is a simtionplified implementation of STAP, and it has certain space-time processing ability.Its clutter suppressing ability is better than AMTI,especially when the moving target's velocity is slow.By inputting the simulating data into the system and analyzing the result,it shows that the system is effective.
