Application of fuzzy pattern recognition for submarine threat level estimation

As the improvement of stealth submarine technology renders,it more difficult to gain accurate detection result by means of a single submarine detection method.A mathematical model of submarine threat level estimation and its procedure and method are pre-sented in detail,more authentic detection result is obtained through fusion calculation of various submarine detection data in terms of fuzzy pattern identification and some valuable conclusions are achieved in the simulation experiment.Therefore,this method has its own theoretical significance and practical value as to enrich anti-submarine technology and to enhance its efficiency.
