Abstract :The technical system of multispectral remote sensing anomaly extraction called de-interfered anomalous
principal component anomaly filtration technology and its working process have been discussed in detail in this
paper. It includes the process of data preprocessing, mask of interferential ground objects, anomaly extraction,
anomaly postprocessing and anomaly filtration. The application of this system in Tianshan-Beishan, Kunlun and
Gandise metallogenic belts shows that it is effective in ore-prospecting work.
