Noise Suppression for Vector Magnetic Anomaly Detection by Noise Spatial Characteristics Investigation

This letter reports a noise suppression method for vector magnetic anomaly detection (MAD) based on noise spatial characteristics analysis. The environment noise indicates space anisotropy that is essential for noise depression. To find a projection direction e that allows the projected noise, den...
