Abstract :
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.
