<p>The purpose of the present invention is to provide an arrival angle calculation device that can calculate an arrival angle to a high degree of accuracy. This arrival angle calculation device (1) comprises a plurality of antennae, a plurality of received signal processing units, and an arrival angle calculation unit. Each of the received signal processing units comprise reception units (12a, 12b), correlation processing units (21a, 21b), peak detection units (22a, 22b), and timing control units (23a, 23b). The timing control units (23a, 23b) are characterised in that when the ratio between the power of the peak period in a period corresponding to an information unit and the power of a period excluding the peak period is larger than a threshold value, signals from the correlation processing units (21a, 21b) are output to an arrival angle calculation unit (24).</p> |
