<p><P>PROBLEM TO BE SOLVED: To provide a radar transmitter-receiver that can be made compact. <P>SOLUTION: The radar transmitter-receiver is provided with: a crystal oscillator that oscillates in a prescribed frequency; a frequency divider for performing frequency division of an output of the crystal oscillator; a transmitting part for outputting a radar signal; a switching power supply for feeding current to the transmitting part; a receiving part for receiving a reflected wave to the radar signal outputted from a transmitting circuit; and a control power supply part for feeding current to the receiving part, and sets a fundamental frequency of switching of the switching power supply and a receiving band of the receiving part so that the receiving band of the receiving part may be placed between an n-th harmonic frequency of the fundamental frequency of switching in the switching power supply and an (n+1)-th harmonic frequency. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
