摘　　要：SAR卫星体系是国家高精尖战略中重要的组成部分,如何准确地仿真SAR卫星成像流程,模拟SAR卫星运行状态,是目前亟待解决的问题。目前相关仿真技术存在成像流程覆盖不完整、数据流转状态不全面等情况,基于上述背景,提出一种面向SAR雷达多模式成像数据流的仿真方案,分析成像数据流特点,构建数学模型,在此基础上对比多种成像模式与运行模式,将流程分解,围绕雷达信号发出、回波接收、数据处理、数据监控以及链路传输等环节,设计目标成像多模式仿真算法、数据处理与传输多模式仿真算法,实现SAR雷达成像数据流仿真,为在SAR雷达成像领域开展的科学研究和实验分析提供强有力的数据支撑和仿真呈现。The SAR satellite system is an important component of the national high-precision and cutting-edge strategy.How to accurately simulate the imaging process of SAR satellites and simulate their operational status is currently an urgent problem to be solved.At present,there are problems with incomplete imaging process coverage and incomplete data flow status in related simulation technologies.Based on the above background,this paper proposes a simulation scheme for multi-mode imaging data flow of SAR radar,analyzes the characteristics of imaging data flow,constructs a mathematical model,and compares multiple imaging and operation modes,decomposes the process,and designs a target imaging multi-mode simulation algorithm around radar signal transmission,echo reception,data processing,data monitoring and link transmission.The multi-mode simulation algorithm of data processing and transmission realizes the simulation of SAR radar imaging data flow,and provides strong data support and simulation presentation for scientific research and experimental analysis in the field of SAR radar imaging.
