Digital Design Method of Target Judgement Model for Underwater Active Acoustic Detection System

The judgment model plays a crucial role in the digital design of underwater active acoustic detection systems. This paper analyzes the signal characteristics processed by hydrophones and analog signals, and proposes a method for determining the presence of a target. Utilizing the Matlab-Simulink platform, we adopt a digital model design approach. Virtual verification of the model demonstrates its effectiveness in accurately identifying target occurrences.
