中文摘要：

针对频率步进雷达多个相邻脉组回波进行互相关分析,得到目标运动参数的一种估计方法.对该方法进一步分析发现,加速度估计误差将导致速度估计产生较大的偏移,为此提出一种复调制细化分析（ZFFT）的简化算法,以较小的运算量实现了加速度估计精度的明显提升,降低了速度估计误差.计算机仿真结果表明,通过互相关分析与ZFFT算法,可准确估计目标的径向加速度和速度,对原始信号进行有效补偿,从而获得高质量的高分辨力一维距离像.

英文摘要：

An estimation method of target＇s motion parameter based on correlation of sequential echo bursts of stepped-frequency radar is presented.Further analysis indicates that the estimation error of acceleration will lead to notable deviation of velocity estimation.To reduce the estimation error of velocity,a simplified ZFFT is brought forward.ZFFT can remarkably improve the accuracy of acceleration estimation with small computation load.Simulation results show that the proposed method can estimate accurately the motion parameters and effectively compensate the raw signals from target＇s motion to achieve the high resolution range profile.
