摘要:
在超分辨测向领域 ,阵元位置误差往往会导致测向性能急剧下降 ,因此必须进行有效的校正。该文基于子空间基本原理 ,提出了一种有源校正法 ,其优点在于收敛速度快、所需校正信号的方向不必准确已知。计算机模拟结果表明 ,采用该方法完成误差校正之后 ,通过修正的MUSIC算法就能实现对信号DOA的精确估计
Abstract:
In super-resolution direction-finding, array sensor position uncertainties often degrade its performance seriously, thus effective calibration procedure is indispensable. Based on subspace principle, this paper presents a new calibrat ion approach with transmitting signals. The method showns that its convergent rate is fast and directions of calibration signals need not be precisely known. Simulational results prove that, if the error is compensated by using the new method, signal DOAs can be accurately estimated with the modifiedMUltiple SIgnal Classification algorithm.
