通过引进一个确定的噪声模型,来改进基于Wiener滤波方法的低纬度磁极计算技术。假设噪声功率是信号功率中固定的一小部分。这使得该技术完全自动化。通过要求将经磁极计算后的波场映入到观测波场中,我们能对该技术作进一步的改进。这是通 By introducing a certain noise model to improve the Wiener filtering method based on low latitude magnetic pole calculation technology. The noise power is assumed to be a fixed fraction of the signal power. This makes the technology completely automated. By requiring that the wavefields calculated by the poles be mapped into the observed wavefield, we can make further improvements to this technique. This is a pass
