| Abstract: | Taking the features of Controlled Accurately Seismic Source （CANS） into account, various design methods of chirp signal for CASS are discussed, and a new method with fitting of discrete points to design chirp signal for CASS is given out in this paper. It is demonstrated that the new method is able to design better chirp signal for CASS assessed by radiated spectrum and energy, wavelet of cross-correlation. It is practicable and meaningful in improvement of phase resolution in actively seismic monitoring. |
