Simultaneous radiometric measurements at 32 GHz and 90 GHz
Abstract
A preliminary evaluation of ground radiometry at 11, 32, and 90 GHz from a stationary 21-m-high platform is presented. Weather parameters (sky temperature, air temperature, air moisture, soil temperature, and air pressure) were measured concurrent with brightness temperature determinations of various man-made and natural objects. Parameters were recorded in both horizontal and vertical polarizations over a range of radar incidence angle from 0 to 90 deg. Some correlation between weather variables and object brightness was observed.
