DEVICE, SYSTEM AND METHOD FOR CALIBRATION OF RADAR TARGET SIMULATORS

摘要

In a first embodiment, a radar target simulator (10) configured to generate a virtual target for testing a radar under test (90) is disclosed. The radar target simulator comprises a radio frequency part (20) configured to operate with signals at a radio frequency and an intermediate frequency part (40) configured to operate with signals at an intermediate frequency and a target simulator (50) configured to receive a signal, apply at least one intended modification at the signal and output the signal after applying the at least one intended modification. The radar target simulator further comprises an antenna (30) configured to receive a signal radiated by the radar under test and send the signal through a first signal guider to the target simulator and receive from a second signal guider a signal that is output by the target simulator and radiate the signal such that it can be received by the radar under test. The radar target simulator further comprises a calibration port (62) connected at the intermediate frequency part.
