跳频脉冲雷达目标的运动参数估计
ESTIMATION OF TARGET MOTION PARAMETER FOR HOPPED-FREQUENCY PULSE RADAR
-
摘要: 本文分析了目标运动对跳频脉冲雷达相参合成目标一维距离像的影响，并在此基础上提出了一种以最小波形熵为准则的最优运动参数估计方法。仿真结果表明，该方法测速精度高，抗噪性能好，可在目标距离信息未知时，实现对目标速度的精确测量。

Abstract: The effect of target motion on a synthetic range profile produced by a hopped-frequency radar is analyzed,and then a method for optimal estimation of motion parameter of targets is presented based on the least waveform entropy rule.Simulation results indicate that the method can accomplish accurate estimation of motion parameter of targets with a good anti-noise performance. -
