  • Radar rangefinder
    Patent number: 6400311
    Abstract: The inventive radar rangefinder has a transmitting/receiving antenna (22) for surveying a danger area. Said antenna is located in a radome housing (12), on a rotatable platform (18). A reflector is placed at a known distance in order to calibrate the device. This reflector is formed by an auxiliary antenna (24) with a connected delay line (26) inside the randome housing (12). The length of the virtual distance of the reflector produced then corresponds to the velocity factor of the delay line used.
