Abstract
In the paper, the combination of the correlation detection method and the chaotic method is analyzed. This new weak sine signal detection system exerts its own advantages. Theoretical analysis and simulation results show that the detection system is very sensitive to bi-frequency weak signal which is covered by strong noise and has a strong ability to restrain the Gaussian white noise. The sine signal with the lowest SNR below -73 dB was detected in simulation tests.
