摘　　要：激光雷达的运动目标定位关键在于准确估计运动目标方位参量,为了提高目标的定位精度,提出近场源三维参量联合估计的激光雷达运动目标定位算法。首先构建了激光雷达对运动目标定位的近场源模型,对近场源中运动目标的每个信源参数自动配对,然后对采用激光雷达检测技术进行目标回波信号检测,结合频率、角度和距离三维参量联合估计的DOA算法实现运动目标的准确定位。实验结果表明,本文提高了激光雷达运动目标参量估计的精度,而且定位的速度也得到加快。By adopting the laser radar technique is the key technology of moving target location lies in the accurate estimation of the parameter of moving target range, in order to improve the positioning precision, put forward a laser radar for moving target location near field source model are constructed based on 3-D near field source parameters for the joint estimation of laser radar target localization algorithm, each source of moving targets in the near field source parameters are automatically paired, by adopting the laser radar detection technology target echo signal detection, combined with frequency, angle and distance three-dimensional parameter joint estimation of DOA algorithm to achieve the accurate positioning of target motion. The experimental results show that the proposed algorithm is used to estimate the parameters of the laser radar moving target with high accuracy, and the positioning accuracy is better.
