DETERMINATION OF EARTH SURFACE FROM TRMM SATELLITE IMAGES

摘要

The Precipitation Radar (PR), on board of the TRMM satellite, provides many information and measurements related to the weather above the earth. Images are produced from reflectivity measurement of different particles and materials. Determination of earth surface level is required when investigating detection methods using TRMM PR data, such as detection of oil and underground water below the earth surface. In this paper, two techniques were proposed for detecting exact earth location from TRMM satellite rays reflectivity. First technique is based on satellite reflectivity images and the second one is based on the reflectivity data itself. The former performed better than the latter in estimating the earth surface level. This finding can facilitate oil and underground water detection.
