<p>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 d1, d1 being 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 d2, d2 being an integral multiple of d and greater than d1. A first azimuth detector detects, within a first azimuth detection area whose angular range is defined by d1, 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 d2, the azimuth of the target based on the second signals.</p> |
