Abstract :
This paper firstly analyses noise modulation of signal and noise restrain characteristic of MUSIC algorithm based on the condition of signal number under-estimation, then proposes a novel valid weak signal detection method: firstly construct a data array by using a high-speed and parallel sampling data to detect weak signal by MUSIC algorithm. Its validity has been tested by simulation.
