    SASS measurements of the Ku-band radar signature of the ocean (1982)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: SeaSat-A Satellite Scatterometer (SASS) measurements of normalized radar cross section (NRCS) have been merged with high quality surface-wind fields based on in situ, to create a large data base of NRCS-wind signature data. These data are compared to the existing NRCS-wind model used by the SASS to infer winds. Falso-color maps of SASS NRCS and ocean winds from multiple orbits show important synoptic trends.

    A survey of oceanographic satellite altimetric missions (1984)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: Consideration is given to the potential benefits of satellite altimetry measurements for oceanographic studies. The technical specifications and instrument payloads of past and future satellite altimetric satellite missions are described in a table. The missions include SKYLAB (1973); GEOS-3 (1975); and SEASAT (1978). Consideration is also given to the NROSS (1988); GEOSAT-4 (1984); and POSEIDON (1987-88) satellite missions.

    Flight measurement and analysis of AAFE RADSCAT wind speed signature of the ocean (1984)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: The advanced aerospace flight experiment radiometer scatterometer (AAFE RADSCAT) which was developed as a research tool to evaluate the use of microwave frequency remote sensors to provide wind speed information at the ocean surface is discussed. The AAFE RADSCAT helped establish the feasibility of the satellite scatterometer for measuring both wind speed and direction. The most important function of the AAFE RADSCAT was to provide a data base of ocean normalized radar cross section (NRCS) measurements as a function of surface wind vector at 13.9 GHz. The NRCS measurements over a wide parametric range of incidence angles, azimuth angles, and winds were obtained in a series of RADSCAT aircraft missions. The obtained data base was used to model the relationship between k sub u band radar signature and ocean surface wind vector. The models developed therefrom are compared with those used for inversion of the SEASAT-A satellite scatterometer (SASS) radar measurements to wind speeds.

    Archival of aircraft scatterometer data from AAFE RADSCAT missions (1983)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: Aircraft scatterometer data obtained over the ocean with the Radiometer-Scatterometer (RADSCAT) instrument is documented. The normalized radar cross section data was obtained at 13.9 GHz for a variety of ocean surface wind conditions, which are also presented. All such valid RADSCAT ocean scatterometer data for which surface truth was obtained are included, except for ice research missions during the last year of RADSCAT's lifetime. Aircraft scatterometer data obtained for the SEASAT underflights were with a second instrument, the Airborne Microwave Scatterometer (AMSCAT). The RADSCAT data are archived on card image computer tapes and on microfiche.
