Abstract :
An important consideration for remote sensing measurements at 1.4 GHz (L-band) is radiation from extraterrestrial sources such as hydrogen. Unlike the cosmic background, this radiation is spatially and temporally variable in the local sky. Radio astronomy surveys are employed to produce maps of equivalent brightness temperature with sufficient spatial and radiometric accuracy to improve approximations which have been used in the past
