Reduction of False Alarm Probability in the Measuring Node of the Hydroacoustic Monitoring System

The probability of a false alarm in the measuring unit of the hydroacoustic monitoring system can be reduced if the primary identification of the signal source is carried out. For this purpose, it is necessary to provide for the presence of noise portraits of targets in the database node. The signals from the pre-amplifier output of the measuring unit are compared with the signals stored in the database by calculating the standard deviation. The signal with the minimum deviation and its corresponding source are determined. Comparison of signals can be made by calculating the correlation function. This article presents the results of computer simulation of the primary classification unit of the measuring unit in the MATLAB&SIMULINK system. The compared signals are represented in the time domain.
