研究多目标环境下,合成宽带雷达速度估计和运动补偿的实现方法.分析了当各目标速度不等时,速度估计的前提条件——目标匹配配对.基于单脉冲雷达体制,将目标匹配的过程扩展到角度域,提出了角度匹配测速法,实现对多个目标不同速度分量的解算.从匹配概率和速度估计的Cramer-Rao下界等方面,对该方法的性能进行了分析.计算机仿真结果表明,该方法有效可行.
The method of velocity estimation and motion compensation of synthetic wideband radar in multi-target environment is studied.The precondition of velocity estimation-target matching matching is analyzed when the target velocities are not equal.On the basis of single pulse radar system, the process of target matching The angle matching velocity method is proposed to solve the problem of different velocity components of multiple targets.The performance of this method is analyzed from the Cramer-Rao lower bound of matching probability and velocity estimation, etc. The results of computer simulation It shows that this method is effective and feasible.
