摘　　要：连续波雷达的测距精度较差,只利用目标的位置量测进行航迹起始的传统方法效果有限。但连续波雷达还能提供高精度的径向速度量测,因此推导了目标径向速度与方位角和航向角之间的关系式,进而建立了2种径向速度波门,结合位置扇形波门,确定了一种利用径向速度量测的航迹起始新算法。仿真结果表明,对低测距精度的目标,该算法航迹起始效果要大大优于单一位置波门算法的航迹起始效果。Range measuring precision of continuous wave radar is poor, and conventional track initiation algorithm using only position information has limited effect. But continuous wave radar can provide high precision radial velocity information, so a formula of relation between target radial velocity and its azimuth and course-angle is derived, and two kinds of radial velocity tracking gate are presented. Simulation results show that the track initiation effect of the algorithm is better than the single position gate algorithm in tracking low ranging precision target.
