摘要

针对弹载SAR在成像过程中复杂的运动状态,建立了斜视匀加速运动模型,在此基础上,通过补偿运动误差,将运动模型简化为正侧视匀速运动模型,进而应用经典CS算法,对点目标进行成像。仿真结果表明该方法可有效完成加速度补偿,实现点目标的清晰成像。

Abstract

A squint constant acceleration movement model was built for the complicated motion state during imaging process of missile-borne SAR. Based on it, the movement model was reduced to side-looking constant speed model by compensating motion error, after which typical CS algorithm was used to image the point target. Simulation results show that the method can excessively compensate the acceleration and image the target clearly.

Key words： missile-borne SAR; acceleration movement model; constant speed movement model; CS algorithm; motion error compensation
