METHOD OF DETERMINING COORDINATES OF THE PLACE OF FALLING OF AMMUNITION Russian patent published in 2020 - IPC F41J5/00 G01V1/24 G01V1/30 

FIELD: measurement.

SUBSTANCE: invention relates to methods of determining ordnance coordinates of ammunition drop. Distributed converter of seismic vibrations, represented by optical fiber, is placed into the ground of the measuring platform. Distributed converter of seismic vibrations is laid in soil so that in two and more directions at least two parallel lines are laid. Distributed converter of seismic vibrations is connected to measuring module located at safe distance from measuring platform. Distributed seismic vibrations converter is programatically divided into measurement sections and measurement points are set, each of which acts as a separate seismic oscillation receiver. Operating mode of the measuring module is adjusted in accordance with the optical length of the distributed converter of seismic vibrations and its binding is carried out to the area. Parameters of test seismic vibrations are measured and analyzed. Measuring module is calibrated. Munitions are fired by measuring platform. Parameters of real seismic vibrations caused by falling of ammunition are measured. Points of primary action of seismic vibrations on each of lines of the distributed converter are determined. Calculating points of primary effect of bearing on center of formation of seismic vibrations. Center of formation of seismic vibrations in the plane of the distributed converter filling from the measurement points is determined. Coordinates of the epicenter of seismic vibrations, where the ammunition falls, are calculated.

EFFECT: high accuracy of determining coordinates (points) of ammunition drop.
