METHOD FOR IDENTIFYING FIRE WEAPONS BY ACOUSTIC VIBRATIONS AT RANGE OF 500 m Russian patent published in 2023 - IPC G01S5/18 

FIELD: fire weapons.

SUBSTANCE: time of arrival of the acoustic wave at the sensor is recorded, whereas measurements are made of the rise time of the excess pressure generated by the shot of the fire weapon from the moment the acoustic wave arrives to the peak value, from the measured values of the rise time of the excess pressure the energy of the source is calculated, its caliber and its identification is carried out.

EFFECT: providing the ability to accurately determine the firing point of a supersonic projectile at a considerable distance.
