METHOD OF DETERMINING THE COORDINATES OF AN AMMUNITION MOCKUP DROP POINT BY A LASER MEASURING DEVICE Russian patent published in 2019 - IPC F41J5/00 

FIELD: test technology.

SUBSTANCE: invention relates to fire complexes testing, in particular, to estimate ammunition mockup accuracy. To determine the coordinates of the point of fall of the mock-up of the ammunition by means of a laser measuring device, a reflector is installed in the center of bombing target (1). At least 50 m from the center of the target on area (3), a laser measuring device is installed, oriented towards the center of the reflector, measuring the azimuth (Am) of the center of the target, then from the laser measuring device, the probing laser signal is emitted to the reflector which is reflected from it in the reverse direction. Laser measuring device receives the reflected laser signal and measures the time interval between the probing radiation and the reception of the reflected laser signal. Measured range is displayed on built-in indicator in laser measuring device. Reflector is moved at a distance of not less than 50 m from the center of the target, performing a mockup throw-off, placing the deflector in the point of falling of the mockup of the ammunition, aligning the laser measuring device on the center of the reflector, azimuth (At) of ammunition mockup drop point is read. Laser measuring device emits a probing laser signal to a reflector which is reflected from it in the reverse direction. Laser measuring device receives the reflected laser signal and measures the time interval between the probing radiation and the reception of the reflected laser signal. Obtained values of azimuth (Am), range (Dm) of target center (1) and point of ammunition mockup drop (At, Dt) are used to determine azimuth and radial deviation of ammunition mockup drop point (Az, R).

EFFECT: high accuracy of determining the coordinates of the point of fall of the munitions mock-up without additional means of optical observation from different sides of the target field in the absence of radiation and seismic vibrations at the moment of ammunition mockup impact on the ground.
