A system for accepting radar signals containing information simulating target range in time and amplitude, target velocity as a doppler, and target signature as an amplitude scintillation and adding target angular simulations of target space position and scintillations is described. An acousto-optic modulator is provided wherein a radar signal containing selected target simulations modulates an optical, infrared signal, in accordance with the selected target simulations. Beam steering mirror galvanometers are provided to selectively direct the modulated IR radiation onto selected areas of an RF (radar frequency) array. The mirror galvanometers in combination with selected areas of the RF array function to add target angular simulations and target space position and scintillations to the other simulations contained in the radar signal. The IR radiation is converted to a radar frequency signal in the RF array and is transmitted to the radar test system.
