MODE OF DETECTION NOISY OBJECTS IN THE SEA Russian patent published in 2007 - IPC G01S3/80 

FIELD: the invention refers to hydro acoustics and may be used in passive sonar systems.

SUBSTANCE: the technical result of the invention is increasing of noise immunity of hydro acoustics system of detection? Realization of prescribed time of accumulation and increasing time of maintenance of acoustics contact with a moving target in the sea. The mode includes the following operations. It is necessary to receive the primary field of noisy radiation of objects with static sheaf of characteristics of direction in the horizontal plane, execute frequency-time processing in each space observation channel, frame, average on time, center and standardize signals to the disturbance, execute observation on the current cycle of survey of received standardized signals and take decision about detection by way of comparison with the threshold value of ratio signal-disturbance. In the process of receiving tracking of energetic parameters of the noisy signal on level, dispersion of the level and selection of local false maximums of noisy signals in the static sheaf of space channels is executed.

EFFECT: increases noise immunity of the passive sonar system of detection.
