SIMULATOR OF FALSE RADAR TARGET DURING LINEAR FREQUENCY-MODULATED SIGNAL PROBING Russian patent published in 2013 - IPC G01S7/40 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to devices for simulating the frequency-time structure of a radar signal reflected from an underlying surface, from one or more targets lying in a fixed direction, and can be used to simulate false targets, including targets near a carrier, for simulating combat performance of a radar system and for simulating echo signals of radar altimeters when probing with signals with different types of linear frequency-modulation. The invention enables to simulate two identical targets independent of the direction and combination of signs of the rate of linear variation of frequency, wherein the first target, which is the primary target, can be simulated in a range shorter than the range of the radar carrier, and the second target will be treated according to range and with appropriate selection of parameters, will not hinder correct monitoring of the primary target.

EFFECT: simulating a target with a range greater than or shorter than the range of the carrier with both analogue and digital processing of the signal without deterioration of quality of the simulated images of the targets.
