摘　　要：本文提出了一种基于冲激雷达体制的数据采集和标量脱靶量测量方法。通过利用波门对回波数据进行采集,得到各波门脱靶距离及其脉冲个数差的观测数据。对观测数据进行二次曲线拟合并估计出二次曲线系数,从而得到标量脱靶量的最优估计。仿真结果表明,该测量方法具有较高的测量精度,可以得到满意的标量脱靶量估计结果。The methods of data collection and miss distance measurement based on impulse radar are presented in this paper. The impulse radar collects return signal by range gates, which gets the data of distance corresponding every range gate and difference of impulse number betweem range getes. Then the miss distance can be estimated by fitting the collected data into conic. Simulations show that the measurement method has satisfying result for the parameter estimation of miss distance.
