中文摘要：

针对频率步进雷达目标运动参数估计问题,提出了基于调频傅里叶变换方法估计目标的加速度和速度,实现运动补偿。在分析匀加速运动对目标一维距离像影响的基础上,采用直接相位一阶差分法,并运用调频傅里叶变换分别精确估计目标加速度和速度,并完成对目标回波的运动补偿。计算机仿真实验进一步说明了文中所采用方法的有效性,并具有一定的抗干扰能力。

英文摘要：

In view of accurate estimation of motion parameters for the stepped frequency radar’s targets,chirp-Fourier transform method was resented to estimate target’s velocity and acceleration. Based on the analysis of uniformly accelerated motion’s influence on the target range profile,the target’s acceleration and velocity were estimated accurately by the method of the direct phase difference and chirpFourier transform to achieve accurate compensation of target’s motion. Finally,the simulation results proved the validity of the method. It also has a certain anti-interference ability.
