Advanced Low Altitude Infrared Earth Sensors
Abstract
Novel low altitude infrared earth sensors are described. A static horizon sensor utilises the state of art technology in electronics to minimise the effect of radiance gradient by taking ratio of the radiometric signals by a hard wired or micro-processor based system. A scanning sensor is also being developed which scans radially at four edges on earth using a single scan assembly thus reducing errors caused by conventional techniques.
