摘要
提出了一种基于多相位中心天线的动目标检测和成像算法。通过对 3个孔径回波信号进行处理 ,获得两路杂波对消后的动目标信号 ,再对这两路信号分别进行多普勒参数估计和干涉处理 ,确定目标的真实位置、方位向和距离向速度 ,然后对动目标聚焦成像 ;与以往的动目标检测算法相比 ,提出的方法能够获得运动目标的全部参数 ;最后通过计算机仿真验证了该方法的可行性和有效性。
A new method of moving targets detection and imaging algorithm based on multi-phase center antenna is put forward in this paper. After clutter was cancelled by using three apertures, two channels of signals through which moving targets can be detected are gained. Then Doppler centroid and Doppler frequency can be estimated, so both the real positions and velocities of moving targets will be acquired. Finally some typical computer simulation results are presented which illustrate the method's validity.
