摘　　要：介绍了调频步进雷达中多普勒效应对距离像的影响,分析了在调频步进雷达中进行运动补偿的思路,在此基础上提出了一种采用频率步进雷达中最小脉组误差准则的速度估计方法对调频步进雷达中运动目标进行速度估计和补偿的方法。理论分析和计算机仿真结果表明,该方法具有可行性,并兼有测速精度高、抗噪声性能强的优点。The influnce of Doppler effect on target motion in Modulated Frequency Stepped Radar is introduced,the velocity compensation method for Modulated Frequency Stepped radar is analyzed,then a method for estimating target's velocity is presented based on the least burst error rule used in stepped-frequency radar to estimate and compensate the velocity of targets for Modulated Frequency Stepped Radar. The theoretic analysis and simulation results indicate that the method is feasible and can accomplish accurate estimation of target's velocity with good anti-noise performance.
