An antenna device characterized by being provided with a plurality of antenna elements (50) for receiving reception waves arriving from an object, a modulation means (60) for modulating reception wave reception signals output from the plurality of antenna elements (50a-50e) into a plurality of differing frequencies and into phases corresponding to the polarization directions of the reception waves, a synthesis means (90) for combining the plurality of modulated reception signals and generating a synthesized signal, a signal processing means (100, 110) for carrying out prescribed signal processing on the synthesized signal, and an extraction means (120) for extracting reception signals for each frequency and phase from the synthesis signal that has undergone the prescribed signal processing. |
