Abstract
A broadband microwave radiometer of the differential type has been designed by adopting a correlation scheme with a quadrature hybrid coupler and its usefulness experimentally evaluated over 6 to 12.4 GHz. The correlator offers in-phase and quadrature-phase outputs. The advantage of this correlator has been investigated.
