<p><P>PROBLEM TO BE SOLVED: To provide an in-vehicle radar apparatus capable of heightening accuracy in calculating angle information, by improving its angular resolution. <P>SOLUTION: The in-vehicle radar apparatus includes two transmission antennas and a reception antenna array which has a plurality of reception antennas, is configured to alternately transmit waves from the two transmission antennas in a time-division fashion, receives reflection waves from a target which reflects the waves by using respective reception antennas, and obtains the angular information about at least the target by using respective acquired reception data. The reception antenna array is configured such that the plurality of reception antennas are arranged so as to be separated at a spacing d, and the two transmission antennas are arranged so as to be separated at a spacing D from the reception antennas positioned at respective ends of the reception antenna array. The spacing D is set to be an arbitrary value larger than that of the spacing d. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
