摘要
分析了通道失配条件下MUSIC算法测角偏差及方差,推导了单源情况下幅度失配及相位失配引起的测角偏差和方差的具体公式。仿真结果表明,理论分析能准确预测通道失配时MUSIC算法的角度偏差和方差。
Performance of MUSIC algorithm for direction finding in the presence of channel mismatch is analyzed. The concrete formulas of deviation and variance of DOA ( direction of arrival) with only one source impinging on an array are derived in this paper. Simulation results indicate that the formulas derived in the paper are correct.
