METHOD OF RADAR LOCATION DETERMINATION OF GROUND VELOCITY OF NONMANEUVERING AERODYNAMIC TARGET BY SAMPLING PRODUCTS OF DISTANCE AND RADIAL VELOCITY AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC G01S13/58 

FIELD: radio engineering, communication.

SUBSTANCE: invention can be used to determine the ground velocity of a nonmaneuvering aerodynamic target, mainly in radar location stations (RLS) with coarse measurements of angular coordinates. The measurement data of distance and radial velocity are multiplied, the value of the first increment of the product of distance and radial velocity for the RLS scan period is determined using a digital non-recursive filter (DNRF), the value is divided by the RLS scan period, the square root is calculated from the obtained result. The device implementing the method comprises a series-connected multiplier of distance and radial velocity, the DNRF, a divider by a scan period, a square root calculator.

EFFECT: increased accuracy of the ground velocity determination.
