摘要 主要介绍了阵列三维SAR成像系统的基本理论,讨论一种双侧放置发射阵元的单激励稀疏阵列三维SAR成像系统;利用相位中心近似原理对天线进行优化,推导了阵列三维SAR系统的模糊函数,详细分析了稀疏阵列三维SAR分辨率特性;最后,讨论了三维SAR系统的RD成像算法,并进行了仿真成像。 This paper mostly introduces the basic theory of three-dimensional array SAR system,and discusses a bilateral array of single-place launch incentive dimensional sparse array SAR system;The antennas was optimized by the antenna phase center similar principles.and the ambiguity function of three-dimensional array SAR system was discuss and the resolution characteristics of the system was made a detailed analysis;Then it discuss the RD algorithm for the 3D-SAR and simulates the three-dimensional imaging.
