A method of establishing template database for high resolution radar target identification

The performance of a target recognition method based on template matching depends on the quality of the template database to a large extent. This paper introduces a method of establishing an extensible template database of range profiles based on the minimum entropy rule. The new method guarantees the quality of the template database from two sides: the signal-to-noise ratio and the completeness of the database. And the new database is easy to update and maintain. Experimental results grounded on real data demonstrate that we can get stable and reliable recognition results with the new method.
