METHOD OF LOCATING SHOOTER BY SOUND OF SHOT DURING MOVEMENT OF SHELLING OBJECT Russian patent published in 2019 - IPC G01S5/18 G01S3/80 

FIELD: physics.

SUBSTANCE: invention relates to measurement equipment, in particular to determination of position of shooter on ground during movement of shooting object using sound from shot, and involves its use in movement of troops and equipment on railway and motor transport, during movement in the formation. Method is based on use of sensors sensitive to sound, location of which and number enable to determine coordinates of shot point - shooter, including the distance to the shooter, the angle between the sound sensors direct arrangement and the arrow direction, as well as the inclination angle of the same straight line in the vertical plane. Distinctive features of the method are introduction of corrections to the initial location of sensors due to movement of the object of fire and in accordance with the measured time intervals between the arrival of the sound signal from the shot to the peripheral sensors and the base sensor, measurement of the error of arrival of the signal to two sensors lying in a vertical plane on one straight line. Correction to the measured value is introduced, which depends on the speed of the object and the speed of propagation of the sound wave, as well as on the angle of inclination of the straight line connecting the pointer and the straight location of the three measuring sensors. Ratio for introducing said correction is determined. Introduction of the correction is directly related to the dynamic character of determining the coordinates of the shooter and is necessary to ensure the required accuracy.

EFFECT: technical result is providing the possibility of determining the position of a shooter during movement of object.
