METHOD OF DETERMINING PROJECTILES TRAJECTORIES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01S13/58 

FIELD: radars.

SUBSTANCE: invention relates to radar scanning ballistic objects trajectories. Said result is achieved due to that the proposed method comprises measuring velocities of projectiles, determining the projectiles deviation from a preset trajectory, forming in the direction of the preset projectiles trajectory two equi-doppler directions in mutually perpendicular planes, determining a dependence of the projectile trajectory in time basing on determining the deviation value of the projectile trajectories in equal time intervals, herewith the deviations value is determined relative to the equi-doppler direction on the basis of comparison of the difference of signals from outputs of, respectively, the first and the third, the second and the fourth Doppler radars with preset values, herewith the device implementing the method comprises four Doppler radars, four detectors, four generators of a Doppler echo signal implementation, four generators of a Doppler echo signal implementation, four formers of discrete values of the current projectile velocity, four computers, two comparators, two units for determining a time dependence of the projectiles trajectories.

EFFECT: technical result is expanding information content.
