发明名称 RADAR DEVICE
摘要 <p><P>PROBLEM TO BE SOLVED: To detect the asynchronous state between a receiving local oscillator of a radar device and a DC-DC converter (power source part). <P>SOLUTION: This radar device has a transmission part for emitting a transmission wave to a target, a reception part of a heterodyne system for receiving a reflected wave from the target, and the power source part for supplying the power to the reception part. In the radar device operated in the state where a local oscillation frequency of the reception part is synchronized with a switching frequency of the power source part, when the same peak frequency exists in an output signal of the reception part to a change of the transmission state of the transmission part, it is determined that the local oscillation frequency and the switching frequency are in the asynchronous state. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p>
