In order to match the requirement of a national defense pre-researching project,the approaches used in TAN were studied and a new approach in this dissertation was designed which based on measurement of terrain- entropy and absolute difference to carry out terrain-matching locating function.Experiments testify that the approach can be quite accurate and shows ideal effect when applied in TF/TA.
