摘要

分析了MUSIC算法在信号数估计不足情况下的噪声调制和噪声抑制特性，提出了一种新的微弱信号检测方法:先用随机噪声调制信号，再用MUSIC算法检测微弱信号。通过仿真验证了该方法的有效性。

Novel Weak Signal Detection Method Based on Noise Modulation Theory for MUSIC Algorithm

This paper analyses the noise modulation and noise restrain characteristic of MUSIC algorithm on the condition of signal number under-estimation, and proposes a novel weak signal detection method: first modulate signal by stochastic noise, then detect weak signal by MUSIC algorithm. Its validity is tested by simulation.
