Patent attributes
In an azimuth detecting apparatus, a receiver includes a plurality of first antenna elements and a second antenna element. The first antenna elements are arranged at first intervals d1 to form an array. The second antenna element is arranged to define a second interval d2 between itself and one of the first antenna elements which is located at an end of the array, where d2 is less than d1. A first azimuth detector detects, within a first azimuth detection area whose angular range is defined by d1, the azimuth of a target based on the signals generated by all the first antenna elements. A second azimuth detector detects, within a second azimuth detection area whose angular range is defined by d2, the azimuth of the target based on the signals generated by the second antenna element and the first antenna element located at the end of the array.
