METHOD OF TRACKING TARGET PATH AND RADAR STATION FOR REALISING SAID METHOD Russian patent published in 2012 - IPC G01S13/00 

FIELD: physics.

SUBSTANCE: invention can be used in radar stations when tracking target paths in gates. Signals are collected from the tracked target in a tracking gate using a radial velocity feature. Probing signals consisting of at least three pulses are emitted in directions of the tracking gate. Pulses received in each i-th gate element are processed in a moving target selection (MTS) system (output signal A_MTSi) and a non-coherent storage (output signal A_ANNi); the ratio of output signals is determined: which is compared with a threshold value K_P, set based on the smoothed radial velocity of the tracked target V_r, measurement error thereof σ_v and the amplitude-velocity characteristic of the MTS system used. Signals for which the condition K_Ii>K_P is satisfied are considered to be signals reflected from the tracked target. The rest of the signals are considered to be signals not associated with the tracked target and passive jamming.

EFFECT: fewer false paths owing to more reliable collection of signals from a tracked target in a tracking gate.
