Abstract
In an azimuth detecting apparatus, a receiver includes antenna elements arranged at predetermined intervals d. A first signal producer produces, based on reception signals generated by the antenna elements, first signals which are equivalent to signals generated by antenna elements arranged at first intervals d, dbeing an integral multiple of d. A second signal producer produces, based on the reception signals, second signals which are equivalent to signals generated by antenna elements arranged at second intervals d, dbeing an integral multiple of d and greater than d. A first azimuth detector detects, within a first azimuth detection area whose angular range is defined by d, the azimuth of the target based on the first signals. A second azimuth detector detects, within a second azimuth detection area whose angular range is defined by d, the azimuth of the target based on the second signals.
