“…The environment temperature distribution is mapped to show the areas that exhibit low temperature versus the ones that produce high temperature. In a satellite receive antenna, the conventional 290 o -300 o Kelvin of earth is substituted by the lower temperature of water surfaces over ocean areas, in the process of the antenna temperature integration [1]. This can be used as an input to minimize the antenna pattern in the direction of the land areas, with some relaxation for the antenna pattern over water bodies.…”

This paper studies the concept of improving the satellite link quality by optimizing the pattern of the receive antenna on board the satellite and at the ground terminal to reduce the antenna temperature. Accurate antenna temperature is calculated by accounting for the temperature difference between land and water bodies in the antenna coverage. The optimization process works on the antenna aperture distribution taking into account the temperature distribution in the antenna pattern. Similar concepts can be used for space and radio astronomy applications.
