Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a radar device which can automatically correct distance range without using signal other than transmission signal of reference range pulse and the like, by eliminating a problem that the detection distance range of a radar is reduced in conventional radar devices because automatic correction is done for distance direction measurement accuracy, a calibration period in which reception signal is not used as distance information is provided, and reference range pulses are generated besides the transmission signal in the period. SOLUTION: Leakage 122 of the transmission signal from a circulator 7 is detected with a detector 11. This is output to a signal processor 1 as a distance range 0 trigger, so that distance direction measurement accuracy is automatically corrected without using signal other than the transmission signal of the reference range pulse and the like.
