METHOD FOR DEFINING TEST OBJECT COORDINATES AT EXPLOSION MOMENT Russian patent published in 2008 - IPC G01S5/18 F42B35/00 

FIELD: physics; mining.

SUBSTANCE: method for defining test object (TO) coordinates at explosion moment involves air explosion wave (AEW) detection by explosion wave sensors (EWS) in at least three measurement points (MP) with geodetic tie to spatial coordinate system of test site (TS). At the TS at least one light receiver (LR) and equipment for undisturbed air parametre registration are installed. By LR signal flash moment accompanying TO explosion is registered, by EWS signals moments are registered when explosion wave reaches each MP, and actual energy discharge of explosion is registered. Obtained data are used in calculation of distance from explosion point to each MP with account of undisturbed air parametres and actual energy discharge of explosion. TO activation coordinates are defined by specified MP coordinates and distances from explosion point to each MP.

EFFECT: obtaining spatial coordinates of item explosion, expanded solid angle and enhanced accuracy of coordinate definition up to 4π.
