TRACKING SIGNAL OF A MOVING TARGET'S SIGNAL Russian patent published in 2005 - IPC

FIELD: radiolocation.

SUBSTANCE: namely it refers to arrangements of allocation of Doppler signals of moving targets receiving by a radiolocation station together with signals of passive interference and may be used in the systems of detection, escorting and measuring the speed of moving targets. Increasing of accuracy of filtration and antijamming capabilities of the tracking filter is achieved by the way of reducing influence of passive interferences made by targets moving on low radial speeds with uneven spectral consistence in the expected frequency range. The advantages of the declared decision may visually become apparent at tracking the Doppler frequency and measuring of the speed of a quickly maneuvering target relocating against the background of heterogeneous formations. The tracking filter of the signal of the moving target has a mixer(1), band filters(2,6,11), a frequency discriminator(3), a control block(4), a guided oscillator(5), detectors(7,12), a ranging block(9), subtraction blocks(8,10).

EFFECT: increases of accuracy of filtration and antijamming capabilities of the tracking filter.
