In practical reconnaissance environment, reports with emitter parameter values take on uncertainty, illegibility and contradiction. In order to solve emitter recognition problems in incomplete information system, a new emitter recognition method based on rough set theory is presented in this paper. This recognition method does not change original information and can find decision rules directly from incomplete decision table. Examples of recognizing the radar emitter are given to demonstrate this new method. Experimental results show that this recognition method is effective.
Key words decision rules; emitter recognition; incomplete information system; rough set
