-
摘要: 本文研究了基于数据矩阵的秩校正QR(RRQR)高分辨谱估计方法,给出了该方法估计源方位角误差的一种非渐近方差估计式,理论分析和计算机模拟结果证明了这一结果的正确性。Abstract: A fast high resolution method based on rank-revealing QR decomposition is analysed, and an analytical expression of the variance of the direction of arrival estimation error is presented. Simulation results verify the analysis.
