摘要

简述了多相位中心合成孔径雷达(MPCSAR)原理及其空时不等效的研究现状

对平台速度与脉冲重复频率(PRF)失配引起的成对回波虚像进行了深入研究

从数学上严格推导了成对回波的位置

分析了两种虚像 (欠采样虚像及失配虚像)的形成机理.论文还提出了在频域进行相位补偿以消除这种成对回波虚像的简单方法.给出的仿真实例验证了本文的结果.

Abstract

This paper introduces briefly MPCSAR principle and its current research situation about the nonequivalent relationship between spatial and time

studies the false target image appearing in the form of pairs of echo when the relationship between platform velocity and PRF fails to be matched.The location formulas for pair of echo in MPCSAR are deduced strictly.Two types of false image(under-sampling false target image and mismatched false target image) are analyzed.A phase compensation method in frequency domain to eliminate these pairs of echo is proposed in the paper also.The conclusions of this paper are verified by simulation.
