Abstract :
Based on rough set theory, a method to simplify information systems was well studied, and applied to select optimal feature parameters of radar target recognition in this paper. The radar target recognition system is treated as a kind of decision-making information systems. Firstly, the original crude information caught by sensors was transformed to information table. Then, distinguish matrix method was adopted to simplify the table and delete redundant information. Finally, the optimal feature parameter group was mined, and the simple and accurate rules of target recognition were obtained. The validity and advantage of this method were demonstrated by an example.
