Basing 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.
