Underwater target noise recognition in modern sonar design is considered. The target noise is divided into five types, and their characteristics in the frequency domain are described. A fuzzy logic algorithm for passive classification is presented. An expert system based on this inference logic for target noise recognition is introduced. Some test data for the expert system show that it has good performance and can be considered as an excellent tool for auxiliary decision-making by the sonar operator
