摘　　要：针对多频连续波雷达航迹起始问题,提出一种引入径向速度量测的航迹起始新方法.首先从理论上分析航迹起始波门的设计方法;然后详细阐述了引入径向速度量测后的航迹起始算法;最后通过Monte Carlo仿真验证了该算法的有效性,并结合多频连续波体制雷达的测距特点,分固定测距误差与变测距误差两种情况比较了不同波门设计对多频连续波雷达航迹起始效果的影响.Aiming at the track initiation for multiple frequency continuous wave（CW） radar,a new method using the radial velocity measurements is presented.Firstly,the design method of track gate is designed.Then the algorithm for track initiation using the radial velocity measurements is expanded.Finally,the Monte Carlo simulation results show the effectiveness of the algorithm.Moreover,the performance of target tracking is compared for different wavegate design methods from the view of constant ranging errors and changing errors.
