METHOD AND SYSTEM OF DETERMINING SUPERSONIC PROJECTILE TRAJECTORY Russian patent published in 2010 - IPC G01S5/22 G01L23/00 

FIELD: weapons and ammunition.

SUBSTANCE: system for determining supersonic projectile trajectory includes at least two equally spaced sensors which are supported with support structure in certain position and which are affected with blast wave created with supersonic projectile. Each sensor includes the following: spherical body elastically supported with support structure with possibility of its movement at least in two directions, accelerometer arranged in spherical housing and generating the signal in compliance with the force applied to it. Force appears as the result of action of pressure gradient of blast wave, and output signal contains the information on the value and direction of pressure gradient and time of arrival of blast wave to the sensor. Also each sensor includes processing device of output signals and times of arrival at least from two sensors to calculate the parametres required for determining of supersonic projectile trajectory.

EFFECT: determination by using the sensors of coordinates of shooting point and movement trajectory of supersonic projectile on the basis of information on blast wave only.
