  • a plurality of antenna sub-modules which are separately arranged from each other at arbitrary positions within a preset range, and that function as individual active phased array antennas, and that also function, as a whole, as a single active phased array antenna;

    a control device which forms a reception beam by exciting the plurality of antenna sub-modules and by individually and selectively applying directional control; and

    a reception processor which obtains a beam combination signal by taking in a reception signal obtained by each of the plurality of antenna sub-modules to apply distributed aperture combination processing to the reception signal.
