Abstract
The device includes a transmitting antenna which also serves as a receiving antenna and a separate receiving antenna for receiving the signals transmitted by the transmitting antenna and reflected at the point of reflection, and two data processing units, one for the signals picked up by the transmitting and receiving antenna and transmitted through a circulator and a first mixer, the other for the signals picked up by the receiving antenna and transmitted through a second mixer. The distance measurement is computed using the signals picked up by the transmitting and receiving antenna for distances less than a predetermined threshold and using the signals picked up by the receiving antenna for distances greater than the predetermined threshold.
