Abstract
A broadband microwave radiometer of the differential type has been designed
by adopting a correlation scheme with a quadrature hybrid coupler (QHC) an
d without devices that limit the radiometer bandwidth. We have confirmed it
s usefulness over 6-12.4 GHz by experimental tests. The correlator used in
the radiometer offers in-phase and quadrature-phase outputs. The advantage
of this correlator has been investigated.
