摘　　要：采用AE类型天线座的精密测量雷达在角度标校过程中涉及轴系及误差校正参数的定义、术语、标定方法、校正模型及参数符号等在不同文献、不同型号雷达、不同研制单位存在较大差异。针对这一实际情况,本文具体介绍了轴系和标校误差项的概念,明确了各校正误差的校正思路,简单分析了各误差项产生原理,详细阐述了各误差校正参数符号与校正模型的关系。针对两种校正模型提出了对应的误差校正参数的符号约束,避免了由于误差校正参数标定方法及符号装订错误引起测角超差故障。最后分析并给出了自动化标校中各校正参数的简化计算模型。In view of the as correction models and great differences of the definition, terminology, calibration methods as well parameter symbols related to the shafting and error correction parameters in different literature, radars and development units during the angular calibration of the precision instrumentation radars with the AE-type antenna pedestals, the concepts of the shafting and the calibration error items are introduced in detail, and the correction ideas of each correction error are determined. Besides, the generation principles of each error items are simply analyzed, and the relationship between the correction models and the error correction parameter symbols is expatiated. The corresponding symbol constraints of the error correction parameters are proposed based on two correction models to avoid the out-of-tolerance faults of the angle measuring resulting from the incorrect calibration methods and symbol input of the error correction parameters. Finally, the simplified computation models of each correction parameter are analysed and given during the automatic calibration.
