METHOD FOR DETERMINING DEPTH OF PENETRATION OF ARMOUR-PIERCING ALL-BODY CALIBER AND SUB-CALIBER PROJECTILES INTO THICK-WALLED OBSTACLE Russian patent published in 2017 - IPC F42B35/00 G01S13/58 

FIELD: weapons and ammunition.

SUBSTANCE: method for determining the depth of penetration of armour-piercing all-body caliber and sub-caliber projectiles into a thick-walled obstacle includes a shot by a projectile along an obstacle and the subsequent determination of its velocity by a Doppler locator before and after the hitting of the obstacle. The axis of the pattern direction of the radar antenna is oriented at the smallest angle to the final part of the trajectory of the projectile. The speed of the projectile is determined by the signal reflected from its bottom tail section. The penetration depth is determined by integrating the dependence of the velocity of the projectile from the start of the deceleration to the zero value obtained from the measurement results.

EFFECT: method allows to increase the accuracy of the velocity measurement of the projectile, to obtain more reliable information in assessing the breakdown effect of projectiles.
