Virtual distance test techniques for radar applications

摘要

A testing device for testing a radar device. The testing device may be configured to determine a first frequency difference between a frequency of a first signal or a second signal and a frequency of a third signal based on a first distance value; transmit to the radar device the first signal; receive the second signal from the radar device; transmit to the radar device the third signal at an offset relative to at least one of the first signal and the second signal based on the first frequency difference; and receive from the radar device a fourth signal indicating a second distance value or a second frequency difference between the frequency of the second signal and the frequency of the third signal, determined by the radar device, for comparison with the first distance value or the first frequency difference.
