ABSTRACT:
The present invention provides a radar apparatus, which can diagnose failure at low cost with high accuracy, and a failure diagnosis method thereof. An antenna serves as both a transmit antenna and a receive antenna. A transmit and receive select switch switches the transmission and reception of the antenna. A control unit measures a power value based on an output signal of a receive wave received by the antennas, and judges that the transmit and receive select switch fails when this power value exceeds a threshold.
