As there is some bad effect in TEM explore, such as the noise,weak signal, primary field.For better survey effect,it is of utmost importance to data preprocessing.Now we go into these data preprocessing problems—data composite filter,and the enhanced process for weak information,and anomaly separation.Some case history result appeared.
