Abstract A glint simulator is disclosed for receiving and reflecting impinging radar energy to simulate the results of a real target. This allows ready monitoring of a radar response to angle and amplitude scintillation error. A single point source of angle scintillation or glint from the simulator may comprise a microwave antenna, a modulator, a noise modulation source and a modulation phase adjustment. Several simulator point sources may be utilized with a single noise modulator to provide a variable multiple-point target. Simulator antennas receive the radar energy, couple it through respective modulators wherein noise modulation may be introduced to reduce or enhance the energy, and reflect it back to the radar.
