Abstract:

	A sensor will be designed for satellite observations of precipitation, sea surface,
and atmospheric soundings. This sensor will comprise a common aperture antenna and
a Gaussian-optics, frequency multiplexer that will be used with low-noise receivers.
The user will be able to scan in two orthogonal polarizations over one decade of
frequency at both microwave and millimeter wavelengths. The design approach is to
mate a compact, broadband, frequency multiplexer with a high resolution antenna.
The expected design is one which would be cost efficient by allowing many bands to
be observed simultaneously with one instrument.

Potential Commercial Application:

Potential Commercial Applications: This system would be used for remote sensing of
many different earth resources, for environmental and weather studies, for navigation,
military operations, and intelligence gathering.
