FIELD: radio engineering, communication.;SUBSTANCE: method comprises measuring range and altitude of a ballistic target through time intervals equal to the scanning period T0 of radar stations; determining an estimate of the altitude of the ballistic target in the middle of the observation interval through weighted summation of N digital altitude measurements; determining an estimate of a second increment of the square of the range for scanning through weighted summation of N digital signals of squares of range; determining the geocentric angle between the radar station and the ballistic target in the middle of the observation interval using the formula where rmd is the range to the ballistic target in the middle of the observation interval, RE is the radius of the Earth; determining gravitational acceleration in the middle of the observation interval using the formula where g0 is the gravitational acceleration on the surface of the Earth; determining the modulus of the velocity of the ballistic target in the middle of the observation interval on an unperturbed passive area of the trajectory using the formula ;EFFECT: high accuracy of determining the modulus of velocity of a ballistic target in ground-based radar stations with rough measurements of elevation and bearing angles.;4 dwg, 2 tbl
