摘要: 该文给出了双基地相位中心偏置天线(DPCA)技术的空间几何模型，从接收信号模型入手分析了双基地DPCA技术的杂波抑制原理，并给出了计算机的仿真结果。文章指出，双基地DPCA技术要求天线间隔D，脉冲重复频率PRF以及载机速度Va三者严格满足条件：D=mVa/PRF (m 是一正整数)，这跟单基地情况下是一致的；当约束条件不能满足时，杂波的抑制效果将受到一定的影响。Abstract: This paper gives the geometry of bistatic radar DPCA(Displaced Phase Center Antenna) technique based on two-antenna .The computer simulation results are also given. The bistatic radar DPCA technique requires that the spacing between the phase centers of the two antennas D is made equal to mVa/PRF, where is a positive integer, is the pulse repetition frequency and is the velocity of the moving platform, just as the monostatic case. When the condition D=mVa/PRF is not satisfied, clutter cant be cancelled completely.
