WebPassive sensors record radiation reflected from the earth's surface. The source of this radiation must come from outside the sensor; in most cases, this is solar energy. Because of this energy requirement, passive solar sensors can only capture data during daylight hours. WebA synthetic aperture radar (SAR) is an active sensor that first transmits microwave signals and then receives back the signals that are returned, or backscattered, from the Earth’s surface. Flight and Directional Terminology The instrument measures distances between the sensor and the point on the Earth’s surface where the signal is backscattered. nova health junction city oregon providers
