在分析当前雷达系统误差校准方法的基础下,利用多海域实验数据,对雷达系统误差在海上的分布特性进行了系统的分析。文中利用雷达与舰船自动识别系统(AIS)信息得到误差分析所需的系统误差序列,通过K-S检验、分布拟合以及变量拟合等方法对系统误差的数值统计特性、相关特性以及区域分布特性进行具体实验分析。该文对精准实施雷达系统误差校准工作有重要的现实指导意义。

Based on the analysis of the current radar system error calibration method, the multi-sea area measured data is used to systematically analyze the distribution characteristics of radar system error at sea. Firstly, the radar and auto indertification system (AIS) information are used to obtain the systematic error sequence required for error analysis. On this basis, the K-S test, distribution fitting and variable fitting method are used to analyze the numerical distribution characteristics, correlation characteristics and regional distribution characteristics of the systematic error. The work done has important practical guiding significance for the accurate implementation of radar system error calibration.
