Abstract: Aiming at the problem that the evaluation methods of the result of recognition of radar emitter signals are messy and the evaluation index is single, a new evaluation system structure of the signal recognition result is put forward. The measurement of recognition rate is used in the radar emitter signal sorting and recognition effectiveness evaluation, and the evaluation index system is constructed based on the measurement of recognition rate, the hierarchy model of evaluation index is also established. Fuzzy comprehensive evaluation method is used into the evaluation, and computer simulation is done to evaluate three recognition methods. Simulation result validates that the evaluation model is effective and has application prospect.
