<p><P>PROBLEM TO BE SOLVED: To provide a radar device capable of minimizing effect of interference waves even when a strong interference radio wave is generated, for example, by directly receiving radar from an oncoming car, and accurately measuring a distance and an angle. <P>SOLUTION: A transmitting and receiving unit 100 of the radar device includes: an antenna element 101; a weight adjustment unit 102 for adjusting at least one of the phase and amplitude of a signal to the antenna element 101; and an addition unit 103. A control unit 104 includes: a transmission and reception control unit 104c for switching transmission and reception of radar by an antenna unit; an interference wave detection unit 104a for detecting an interference wave received by the antenna unit; and a null direction control unit 104b for adjusting the direction of a directional null point of the antenna unit by controlling a weight adjustment unit 102 when the interference wave detection unit 104a detects an interference wave. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
