<p><P>PROBLEM TO BE SOLVED: To accurately detect the azimuths of objects by a simple constitution in beam scanning radar equipment. <P>SOLUTION: The beam scanning radar equipment is provided with a transmitter; an antenna shared for transmission and reception; a receiver; a transmission/reception switching means for switching the antenna shared for transmission and reception between transmission and reception; an antenna scanning means for controlling the beam scanning direction of the antenna shared for transmission and reception; and an azimuth angle computing means for determining the azimuth angles of objects. The azimuth angle computing means determines an azimuth angle estimated curve P(θ) passing through points (θ<SB>1</SB>, P<SB>1</SB>), (θ<SB>2</SB>, P<SB>2</SB>), and (θ<SB>3</SB>, P<SB>3</SB>)through the use of data on them comprising antenna angles and reception levels and determines an antenna angleθ<SB>m</SB>of a point M at which the reception level of the azimuth angle estimated curve P(θ) is maximum as the azimuth angle of an object. Since the azimuth angle of the object is determined on the basis of the azimuth angle estimated curve P(θ), it is possible to accurately detect the azimuth of the object on the basis of a few items of data. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
