分析了影响航管二次雷达测角、测距精度的主要因素及误差大小,实际应用中其误差因素的改善受雷达系统硬件条件限制,难以实施.文中从二次雷达数据处理角度给出了改善雷达测量精度的有效方法,其内容包括OBA表自校准技术、最小二乘法测角、测距误差修正等.上述方法经工程应用验证,可有效提高二次雷达的测量精度.

Main factors which affect secondy suveillance radar(SSR) measurement accuracy and calculates values of measurement errors are analyzed in this paper firstly.Generally it is difficult to apply some improving methods to decrease the errors because of the radar hardware system limitation.From point of view of radar data processing,we propose some valid methods to increase measurement accuracy such as the OBA self-correcting technique,the angle measuring method of least square and the error correction of range ...
