摘要：
Circular synthetic aperture radar (CSAR), with high resolution and multi-angular apertures, is an innovative mode which can perform consecutive surveillance and target tracking. The important purpose of moving target tracking is parameter estimation. In this paper, we present a method to estimate the motion parameters and refocus imaging of three-dimensional (3D) moving target. Doppler information and interferometric phase term are the basic of motion parameter. And the estimated results serve as the prior knowledge of refocus imaging. Simulation results demonstrate the correctness of the analysis and the performance of the proposed approach.
