A fuzzy recognition method of emitter based on Variable Precision Rough Set Model

In order to settle the problem of emitter recognition, the method of feature weights setting which applies variable precision rough set model is researched in this paper. Because this weight setting method is completely decided by data itself, it is more impersonal and practical. The description of object classpsila condition attribute in conception positive region can be used to get the plenary condition of this conception. The weights of feature parameters in emitter recognition can be gained by the dependences between knowledge; at the same time, the fuzzy theory is combined to form an emitter fuzzy recognition method based on feature weight by variable precision rough set model. At last, this mixed method is applied in radar emitter type recognition, simulation and the results show it is effective and feasible.
