DEVICE FOR IMITATION OF A FALSE RADAR OBJECTIVE AT SENSING WITH SIGNALS WITH LINEAR FREQUENCY MODULATION Russian patent published in 2017 - IPC G01S7/40 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to devices designed to simulate the time-frequency structure of a radar signal reflected from a underlying surface from one or more targets in a fixed direction and can be used, for example, to simulate false targets, including those located closer than the carrier, to simulate the combat operation of the radar system, as well as to simulate echo signals of radio altimeters when probing with signals with various types of linear frequency modulation. Dynamic modification of simulating the parameters is carried out, as well as in accordance to the parameters of the input sounding signal.

EFFECT: imitation of the target with a range greater than or less than the range of the carrier, regardless of the magnitude, direction, and combination of the signs of the rate of linear change in the frequency of the sounding signal.
