Research of the Weak Signal Detection Technique Based on Cross-correlation Theory and Narrowband Filter

摘要：

Weak signal detection is the essential part of information science, and is applied widely in various fields of science and technology. Paper mainly researches how to extract the useful signal out of the signal polluted by noise. On the basis of the introduction to the cross-correlation theory and method, the paper completes detecting the weak periodic signal with narrowband filter based on phase-locked loop. The innovation is that paper discusses the feasibility of detecting the weak signal based on cross-correlation theory and narrowband filter. At the end, the simulation in MATLAB environment testifies the result meets project needs.
