RADAR SCENE SIGNAL SIMULATOR Russian patent published in 2015 - IPC G01S7/40 

FIELD: radio engineering, communication.

SUBSTANCE: method is carried out by replacing antennae of simulators and drives thereof with an antenna with a mobile phase centre, consisting of N radiators arranged linearly at an equal distance less than the wavelength in the propagation medium of the electromagnetic wave, from which m adjacent radiators at an appropriate moment in time are connected in-phase to a signal simulator through unmatched dividers and unmatched microwave switches, located in the branching feeder line from the divider to the radiator, as well as by introducing into the simulator circuit a register for rewriting the code of the position of the group of connected radiators under control of processor and providing change in the position of the phase centre of the virtual antenna. To simulate multiple targets, the radiation phase centre is moved into multiple positions while processing the signal at the station. The simulator comprises a digital delay line, parameters of which are switched synchronously with movement of the radiation phase centre.

EFFECT: simple device while improving reliability of simulation.
