摘　　要：提出一种基于宽带步进频体制的雷达测量矢量脱靶量测量系统。该系统采用布局成三棱锥结构的4路接收天线阵来接收回波信号,每一路天线采用宽带步进频体制雷达实现距离高分辨,再利用瞬时距离交汇定位法实现目标空间精确定位,最后通过卡尔曼平滑滤波获得目标运动的较精确轨迹。仿真实验表明该定位方法可以使得定位精度在1 m以内。Wideband stepped frequency miss distance measurement system is introduced in this paper.Four pyramid-structured receiving antennas are used in the system in order to receive echo signals.Wideband step-frequency waveform has been used to achieve high range resolution（HRR）.Instantaneous spatial location method is used after range detection.Kalman filtering process let target motion trajectory more accurate.Simulation results show that the error using this method is less than 1 m.
