Spotlight Radiometer

A proposed radiometric instrument denoted the spotlight radiometer (SLR) would operate in a frequency band centered at ≈557 GHz and would scan in a conical or circular pattern. The SLR was conceived for use in obtaining spatially and spectrally resolved indications of CO and H2O molecules in the Martian atmosphere. The basic SLR design is also adaptable to terrestrial use and to operation in different submillimeter-wavelength bands.
