Radar testing device, comprises antennas for receiving and transmitting radar signals, delay lines, amplifier and wave guide circulator, where input and output of amplifier are connected to delay lines

摘要

The radar testing device (30) comprises an antenna (A1), which is arranged to supply a radar signal (R1) received by the antenna into a delay line (C1) and to transmit after a temporary delay as another radar signal (R2). An amplifier (22) is provided, whose input is connected to the delay line and its output is fed to another antenna (A2) with the latter radar signal by another delay line (C2). A waveguide circulator is provided, which is fed at the former radar signal into the former delay line and at the latter radar signal of the latter delay line in the antenna (A1). An independent claim is also included for a method for testing radar sensors with a radar testing device.
