<p>A radar apparatus for vehicles comprising a radar sensor for transmitting and receiving an FM signal and extracting a beat signal, and a relay for offsetting the frequency after receiving this FM signal and transmitting a relay wave. This radar apparatus does not detect a false image depending on leak-in of a DC component in the radar sensor, can avoid the interference due to a direct wave from an oncoming vehicle without using polarized wave isolation and can eliminate the beat signal corresponding to stationary objects.</p> |
