精密可控震源非线性扫描信号优化设计
Optimal Design of nonlinear sweep signal of CASS
摘要
Abstract
Taking the feature of the transmitting signal of the Controlled Accurately Seismic Source (CASS) into account, the different sweep signals with different spectrum could be designed based on the energy balance principle or maximum signal to noise ratio principle. The energy distribution of different frequency is determined by the frequency-time relationship, and the frequency-time relationship is designed with good flexibility base on two principles. The spectrum and correlation wavelet of the designed signal would be improved. Compared with linear sweep signal, the designed signal loses some energy, but improves the resolution. It is meaningful for vibroseis surveying.关键词
