Radar system for measuring the nearest distance to an object

摘要

This radar system for measuring the nearest distance "h" comprises transmitting means (9, 7, 5) for transmitting towards an object a frequency-modulated wave, receiving means (15, 17) for receiving the wave after reflection by the object, mixing means (20) for producing a beat- frequency wave between the transmitted wave and the received wave, high- speed digital processing means (30) for effecting a time-frequency transformation operation of the beat-frequency wave; it further comprises management means (50) for providing the user with the value "h" by influencing more specifically the transmitting means and the high-speed digital processing means.
