| Abstract: | The principle of passive sonar and the detection of passive sonar signal are presented in this paper. The method to detail the spectrum N th Chirp-z transform is analyzed, and the simulation of this method is implemented in Matlab environment. The experiment results indicate that Chirp-z transform could detail the spectrum and improve resolving power of the local frequency band. This algorithm is used to process the passive sonar spectrum, thus making the overall detection performance of the system even better. |
