| Abstract: | A demodulation method of Chirp signal using wideband phase locked loop plus integration detect is proposed. Moreover, its performance is simulated by using Matlab. The results show that the performance of the method is considerable compared with the matched filter demodulation.Furthemore, the method is low cost , highly flexible ,widely application value and easy to integrate. |
