Abstract

Abstract: To find an efficient and convenient method to determine whether a dredging is illegal is a very meaningful research content. A method of detection of throwing sand behavior based on Chirp signal was studied and three implementation schemes (subsection FFT fast correlation), FRFT and DeChirp were designed. The feasibility of the three schemes was verified by Wu Yuan Bay experiment and the simulation results. Anti-multipath and anti-noise performance of FRFT transform is the best. The performance of dechirp is the worst. Through the analysis, it comes out the conclusion: when the multipath effect is serious, FRFT algorithm for detection is recommended; When the multipath effect is small and the requirement of the data real-time processing is strict, subsection FFT fast correlation algorithms for detection is recommended.

Key words: chirp signal, subsection FFT fast correlation, FRFT transform, dechirp pulse compression processing method, detection of throwing sand
