ABSTRACT:
In an in-vehicle mount radar device which has a reception antenna array containing plural reception antennas and two transmission antennas and in which a transmission pulse is time-divisionally and alternately transmitted from each of the two transmission antennas, a reception pulse based on the transmission pulse reflected from a target is received by each of the reception antennas, and at least angle information concerning the target is calculated by using reception data obtained by each reception antenna, the reception antenna array is constructed by arranging the plural reception antennas so that the reception antennas are spaced from one another at an interval d, each of the two transmission antennas is disposed so as to be spaced from the reception antenna located at each of both the end portions of the reception antenna array at an interval D, and the interval D is set to any value larger than the interval d.
