摘要
随着反辐射制导精度的提升,天线罩在探测过程中引入的幅相调制特性变得不可忽视,需通过头罩匹配进行补偿。为提升匹配效率,采用了SATIMO公司的SG系统完成快速测试,但通常情况下其原始数据不满足导引头使用,需做进一步转换。提出一种基于三方转换的坐标变换和插值处理的数据转换方法,可以非常方便地将SG系统下测试得到的幅相数据,转化到任意形式的目标坐标系下。
As the guidance precision of anti-radar is higher,modulation of signal amplification and phase caused by random in radio direction finding could not be accepted as the past.These bad effects could be reduced with pre-calibration.A near field test system‘SG’which produced by SATIMO Co.is used to get an acceptable time in processing.The original data could not be used directly by anti-radar guider because of the coordinate not matching.A calibration data translation method based on tri-coordinate matching and interposition which can give a simple way to covert the original data gotten by SG system into any target coordinate is studied.
