阵列信号处理中一种新的误差分析及其矫正技术
A New Technology to Analyze and Calibrate Errors in Array Signal Processing
摘要
Abstract
In this paper，the mechanism of the performance degration due toChannel Mismatching and Sensor Coupling in Azimuthals and Frequencies is analyzed.To overcome existing methods’limitations that can only compensate one or two influenec factors,a new comprehensive calibration method that can compensate Channel Mismatching and Sensor Coupling is proposed. This method raises the calibration precision greatly.Firstly,we apply the new method to estimate Directions and Frequencies simultaneously,and an important conclusion that these influence factors can not affect frequency estimation is drawn.This method is easy to be implemented and the results of acoustic experiments in anechoic room show that the proposed method is effective.关键词
