摘　　要：针对测距误差从大到小循环变化的二次差频连续波雷达航迹起始十分困难的问题,提出了一种与径向速度及其差值波门和扇形波门配合使用的模糊距离波门用于航迹起始,剔除由于目标径向速度相差不大而产生的虚假航迹.仿真结果表明了该波门的有效性.Aimed at the difficulty in the track initiation of the quadric frequency difference continuous wave radar whose ranging error is circularly changing from big to small, it was proposed that a fuzzy range gate was used in track initiation, where the radial velocity and its difference gate and the sector gate was cooperatively employed, eliminating the false track resulted from the lower difference from target radial velocity. The simulation shows that the gate is of effectiveness.
