摘要
Abstract
The position errors of array elements are discussed while the location of signal source has a deviation.A calibration method is proposed based on the single source and the antenna arrays that are able to rotate accurately.Plenty of samples can be got from those arrays,and the time-sharing calibration effect of multiple sources can be achieved.Firstly,the least square fitting method is used to calibrate source location by removing samples whose fitting error is too large.Then the position errors of array elements are calibrated by using least square method again.At last,the computer simulation demonstrates that the algorithm is ef-fective and practical,and the angles which are measured by using MUSIC spectrum before and after calibra-tion are compared.关键词
