摘　　要：针对一种船载C频段统一测控雷达对塔与对星角度标校数据不一致问题,通过对交叉耦合产生及因近场导致入射场相位不均匀等原理的分析,得出标校数据不一致的问题主要是由于近场效应引起的结论,并通过试验数据对该结论进行了进一步论证,最后对该C频段统一测控雷达下一步角度标校工作给出了合理建议。This paper discussess the data inconsistent problem of a shipborne C band unified TT＆C when radar points at the tower and the synchronous satellite during the angle calibration. Through radar analyzing the cause of cross coupling and the incidence field phase ununiformity due to the near field, it concludes that the inconsistence is caused by near field effect. It demonstrates the conclusion through experiment data and finally gives rational suggestions for the angle calibration for the C band unified TT＆C radar.
