Time-domain method for vortex-geophone's parameters test

给出了基于沃尔什变换的涡流检波器参数测试的时域方法。计算机仿真和试验验证 ,该方法和频域方法相比 ,精度高 ,测试时间短 ,并具有良好的抗噪性。

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.
