<p>PROBLEM TO BE SOLVED: To provide a radar device prevented from the output of erroneous information caused by a DC-DC converter, and confirmable on the normal acting state. SOLUTION: The DC-DC converter is driven to supply electric power to a receiving part of this radar device by intermediate frequency generated by an intermediate frequency generating part included in the receiving part. If necessary, a frequency dividing part may be installed between the intermediate frequency generating part and the DC-DC converter. In this case, the frequency of n-th harmonies of a driving signal of the DC-DC converter coincides with the frequency of the intermediate frequency generated by the intermediate frequency generating part, so that the output of erroneous information caused by driving the DC-DC converter can be prevented.</p> |
