Word Count : 509
Active microwave remote sensing is a technique that involves the transmission of microwave signals from a sensor (usually mounted on a satellite or aircraft) towards the Earth's surface and the measurement of the backscattered signal. Unlike passive sensors that rely on naturally emitted radiation, active sensors generate their own source of energy, making them capable of acquiring data regardless of sunlight and under all weather conditions, including cloud cover, rain, or darkness. There are two main types of active microwave sensors: radar and scatterometer. Among them, Synthetic Aperture Radar (SAR) is the most widely used.
