A system that simulates reflected waves in the laboratory that are observed with a radar from the rear of a car running in front of the observer. Multiple reflective locations can be set in 3D, and the positional relationship of reflection zones also can be automatically controlled according to distance, in consideration of approaching from a long distance.to the left and right. The horn antennas are moveable back and forth and the amount of attenuation is variable, so you can get an image waveform similar to the actual situation.
