APPARATUS FOR SELECTING CLUTTER REFLECTIONS FROM OPTICALLY UNOBSERVABLE OBJECTS ("ANGELS") IN AREA OF "LOCAL" OBJECTS Russian patent published in 2013 - IPC G01S7/36 

FIELD: radio engineering, communication.

SUBSTANCE: prototype having a series-connected intermediate frequency amplifier also includes a matched filter, a "local" object elimination filter, an amplitude detector, a non-coherent storage and an echo signal detector, as well as a plan view display, a first valve and an "angel" selector, consisting of a second and a third valve, a fast Fourier transform device, a Doppler frequency rough estimating device, an elimination filter tuning frequency generating device, a Doppler frequency filter, an elimination filter number determining device, a Doppler frequency determining device and a threshold device with corresponding connections.

EFFECT: protecting a radar station in the area of local objects from echo signals of angels of an arbitrary amplitude, high probability of detecting stealth and small targets.
