摘要
Abstract
The laser Doppler signal has the characteristics of weak intensity, low signal-to-noise ratio and strong noise interference. The basic principles of fast Fourier transform, digital correlation and Welch power spectral estimation are briefly introduced. The simulation and detected laser Doppler signals were processed in Matlab with these signal processing methods mentioned above, and were compared. The results indicate that all of these means can extract weak signal from strong noise background, and the digital-correlation technology can eliminate the noise more effectively. However, all of them have low accuracy. Therefore, a further research on signal processing needs to be done.关键词
