Failure detection apparatus and radar apparatus with failure detection apparatus

Abstract

A conventional millimeter wave radar cannot detect a failure when there is not satisfied the condition that a road exists in front of a vehicle or that in two or more radar apparatuses, a leakage electric wave from another radar can be detected. A failure detection apparatus according to the present disclosure calculates reception power values from a reception processing signal for each antenna and compares the reception power value with a reference power value determined by a reference power calculation unit so as to perform a failure determination. There is provided a failure determination unit that compares the reference power value for a failure determination with the power value obtained from a reception processing signal outputted from each of receivers so as to perform a failure determination for each of the receivers.
