Abstract
A design of a FM/CW system is presented. The transmitting and receiving functions with several polarization combinations are realized by using a mono-aperture compound antenna. The volume and weight are reduced and the area of the sample in the measurement is increased in comparison with the system in which both transmitting and receiving antennas are used. The ability of detection with different polarization combination is improved. This design has been used to the ground based microwave scatterometer.
