Abstract
According to the invention there is provided radar simulation apparatus comprising an oscilloscope having a display screen, said oscilloscope producing a luminous movable screen spot, scanning means connected to the oscilloscope for causing the spot to be scanned over said screen in a radar transmitter type scanning pattern, a photo-detector mounted in front of the screen for detecting light from said spot only when said spot is near the photo-detector and for producing an electrical signal when said light is detected, and modulation means connected to receive and modulate said electrical signal in simulation of a radar pulse repetition.
Claims5
Radar simulation apparatus comprising a cathode ray tube oscilloscope having a display screen, said oscilloscope having means for producing a movable screen spot, scanning means connected to the oscilloscope for causing the spot to be scanned over the screen in a radar transmitter type scanning pattern, photo-detector means mounted in front of the screen and closely adjacent or on said screen for detecting light from said spot only when said spot is near said photo-detector means and for producing an electrical signal when said light is detected, and modulation means connected to receive and modulate said signal in simulation of a radar pulse repetition.
