An apparatus and method for microwave imaging and sounding with large bandwidth radiometer reflector antennas in a compact form. The apparatus comprises a main reflector for reflecting a beam, a polarizer for polarizing the reflected beam into a first polarized beam and a second polarized beam, a first Frequency Selective Surface (FSS) reflecting a first selected frequency of the first polarized beam, a second FSS reflecting a second selected frequency of the second polarized beam, a first feed receiving the first selected frequency and a second feed receiving the second selected frequency. The method comprises reflecting a beam, polarizing the reflected beam into a first polarized beam and a second polarized beam, reflecting a first selected frequency of the first polarized beam, reflecting a second selected frequency of the second polarized beam, receiving the first selected frequency and receiving the second selected frequency.
