METHOD FOR INCREASING INTERFERENCE IMMUNITY OF OPERATION OF ACTIVE HYDROACOUSTIC DETONATING FUSE Russian patent published in 2011 - IPC F42C13/06 

FIELD: weapons and ammunition.

SUBSTANCE: method involves principle of separation of signals supplied to the receiver input both from the target and from interference of various origin into two groups during their analysis and processing. Signals supplied to the receiver input during initial time interval of the specified radiation period of sounding impulses are classified at their analysis as signals from the target. Signals supplied to the receiver input during the final interval of the specified radiation period of sounding impulses are classified as signals of interference of various origin, including flowing noises. Durations of the specified radiation period of sounding impulses, as well as its initial and final intervals, are determined from mathematical equations.

EFFECT: increasing interference immunity of detonating fuse.
