Abstract :
The weak signal embedded in various noises is the subject of weak signal detection, while the noises much stronger than the valuable signal, and must take measures to improve the S/N during measuring the signal. So based on the signal-correlation principle, separates the useful signal from the noises by the measured-method of signal-correlation principle.
