摘要: 基于卫星轨道根数推导了分布式SAR卫星的轨道要素计算公式。建立了分布式SAR卫星的成像空间几何模型，分析了分布式小卫星SAR的模糊函数。针对具体的编队卫星进行了轨道参数设计，给出了轨道设计的结果。在此基础上仿真了不同编队构形、不同卫星数目情况下系统的空间模糊函数，研究了小卫星编队构形、数目和模糊函数的关系，为后续的成像算法研究奠定了一定的理论基础。Abstract: sing on satellite trajectories, the formula of formation flying orbit elements is derived. The imaging geometric model of distributed satellites SAR is presented and the ambiguity function of distributed satellites SAR is analyzed. Moreover, a design example of the space circular formation flying is given. According to the design result, the ambiguity function simulations of distributed satellites SAR with different formation configurations and different satellites are developed. The relation between satellites formation configurations, number and ambiguity function is studied, and it is theory basis of following imaging algorithm research.
