摘要

摘要: 随着对高分辨率和宽测绘带的要求，多发多收合成孔径雷达成为了一个重点的研究领域，其中多孔径同载频，发射正交编码信号是较有可能工程实现的方式之一。该文在详细研究和推导了回波阵列的排列方式和多发多收回波信号相位补偿原理的前提下，提出了4种可能的回波处理方式，给出了这四种处理方式的信号矩阵表达式，并利用具有正交性的混沌编码信号对各种处理方法进行了仿真和数据分析，证明了这些方法的有效性。

Abstract: With the requirement of high resolution and wide swath, multiple-transit and multiple-receive SAR becomes a important research field, multiple apertures use the same carrier wave frequency, transit orthogonal phase coding signal is one of modes, which can be implemented in the engineering . Through the particular research of the echo array and the echo phase compensate four kinds impossible methods of echo processing and the signal matrixes of the methods are proposed. The simulation with orthogonal chaotic coding signal shows the effectiveness of the methods.
