摘　　要：新体制下靶场配备的单脉冲测量雷达系统误差难以满足精度指标要求。文中通过对大量实验数据的分析和研究,提出了系统误差特性分析与回归分析相结合的脉冲雷达误差分离方法。首先,利用误差影响函数,定性分析测量误差模型中各种误差成分;然后,通过模型辨识理论和回归分析方法分离系统误差。用该方法对实测数据进行误差分离,结果表明,该方法能较好地分离出残留误差成分,为设备查找问题提供充分依据,同时有效提高了数据处理结果的精度。In the new geodesic systems, it is unappropriate to realize the high precision from for analyzing the system errors of the measured data from monopulse radar installed in the test range directly. And an errors-separation method for the e data is obtained by studying and analyzing a lot of experimental data, which combines system error characteristic analysis with regression analysis. First, different errors of the measurement error model are analyzed qualitatively using error influence function. Then, different error factors are separated with model identification theory and regression analysis method. This method is used for system error separation of real measurement data. The result proved that this method can separate residual error effectively. Accordingly, enough basis for finding equipment problems can be provided. Also the precision of the data processing is improved significantly.
