<p>Signals received by respective antennas are inputted to a signal processing unit (18). Here, the signal processing unit (18) inputs a desired signal while inputting an undesired signal for a predetermined period. A first array processing unit (152) executes an array process on the inputted signals so as to output a smaller number of signals than the number of the antennas. The first array processing unit (152) derives a weight vector which approaches a vector orthogonally intersecting the undesired signal and uses the derived weight vector for the array processing. A second array processing unit (154) executes array processing on the signal outputted from the first array processing unit (152). The second array processing unit (154) derives a weight vector for the period during which the desired signal is inputted and uses the derived weight vector for the array processing.</p>
