| 摘 要： | 针对噪声对宽带干涉仪测角的干扰,提出了互相关测角算法.该方法避开频域分析,计算简单.通过仿真试验表明其抗干扰较强,具有一定的精度.通过本方法对人工引雷数据分析,能够明显定位直窜先导-继后回击过程,为宽带干涉仪测角提供了一个新思路.

| Abstract: | To solve the noise interference in angle measurement of broadband interferometer,a correlation angle measurement algorithm was proposed.This method avoided complex analysis in frequency domain,which was easy to realize.Simulation tests indicated that it had a good ability of anti-interference,as well as a moderate precision.Data from triggered lightning was also analysed,from which we can obviously locate the process of dart leader and subsequent return stroke.So it provided a new way for angle measurement ... |
