摘要: 通过分析相位中心偏置天线(DPCA)技术和干涉处理的优点和缺点，该文提出了一种用三孔径合成孔径雷达(SAR)对地面运动目标进行检测的新方法。该方法不仅能够检测出动目标，还能够精确估计动目标参数，即确定出动目标的真实位置和运动速度，然后对动目标聚焦成像。该文方法简单，运算量小，通过计算机仿真数据验证了该文算法的正确性和有效性。Abstract: This paper puts forward a new method of detecting three-aperture Synthetic Aperture Radar (SAR) ground moving targets after studying Displaced Phase Center Antenna (DPCA) and interferometric processing technique. This method can not only discover moving targets but also estimate the targets parameters such as real positions and velocities. Furthermore it is simpler and needs fewer computations. Finally some typical computer simulation results are presented which illustrate the methods validity.
