Airborne radar and laser
Airborne radar or lasers (lidar) are active systems that are mounted on aircraft or helicopters. Radar and Lidar are both ranging systems, measuring reflectance and distance of a target from the sensor. In both instruments the sensor transmits and measures a response, using microwave (1mm - 3m) wavelengths for radar and visble to infrared wavelengths for lidar. Interpretation and analysis of these data sets requires a completely different approach to standard optical image data.
