Optical backscatter sensor manual
WebThe SAR sensor is mounted on an airplane or satellite and points sideways instead of straight down (nadir). It is an active sensor that sends electromagnetic waves to the earth's surface and receives the reflected signal. The electromagnetic wave received by the sensor is called the measured backscatter. A SAR image is a 2D rendering of the ... WebOptical Backscatter Sensor (OBS) An OBS measures turbidity by sending a beam of infrared light into the water and measuring the quantity of light scattered off suspended particles and reflected back to the sensor. Calibration coefficients are then employed to determine suspended sediment concentration. OBS are more sensitive to coarse-grained ...
