轴角-数字转换测试的误差分析与数据处理

Error Analysis and Data Processing of the Angle-digital Conversion Testing

通过对某型雷达综合处理机中轴角-数字转换测试系统的系统误差进行研究,论述了该系统误差产生的原因,总结出了误差分布规律,进而提出了一种以平均误差校准法和牛顿插值校准法相结合的新的误差补偿方法.经实验证明,该方法具有误差修正快、计算量小、补偿精度高等优点.

By studying the system error of the angle-digital conversion testing system in a certain radar integrated processor, the cause of system error was given and the law of error distribution outlined, and then a new error compensation method was proposed, which combined the average error calibration method with Newton interpolation formula calibration method. It is proved by experiment that this new method has the advantages of fast error correction, less computation and high compensation accuracy.
