We present a detection scheme of nV-level sine signal, which based on the chaotic theory, prove the principle and method of the chaotic detection to a sine signal, simulation experiments show that the detection low limit decreases to nV-level of a weak sine signal under the background of the free zero-mean value color nois while the chaotic detection system combines with the generator of nV-level sine signal ,which is preposed by this paper.
