ITU Remote sensing is the collection of information on an object or phenomenon from a distance without any physical contact. In the context of Earth science, space- or airborne sensors are used for data acquisition and the subject of these observations are the atmosphere or the surface of land and the ocean. For microwave remote sensing, measurements are made of electromagnetic radiation ranging from below 45 MHz up to a Terahertz or more. Microwave remote sensing can be either passive or active. Passive sensors gather radiation originating from the particular objects under observation. This radiation can either be emission by the objects themselves or energy coming from the Sun and reflected by these objects. ....
