Based on analyzing the actually measured MT data of an ore concentration area in the middle and lower reaches of the Yangtze River and considering the actual situation in the study area, this paper analyzed the profile characteristics of noise and divided the noise into 6 kinds, namely, impulse noise, periodic noise, triangle-wave noise, square-wave noise, step noise and triangular charge-discharge mode noise. The results obtained are helpful to making de-noising treatments directed against different noise types in the late-stage data processing.
