【Abstract】 The method for vortex-geophone’s parameters test in time domain based on Walsh transform is proposed in this paper. Computer simulation and experimentation show that the algorithm in this paper has greater precision, better performance suppressing noise and shorter test time than that in frequency domain.更多还原
