Information on Laser Radar

Laser radar (LIDAR) is a radar that uses light in place of the radio-frequency signals used in conventional radar.
     Advantage of laser radar include its potential for very high azimuthal resolution. Disadvantages include its sensitivity to dust and smoke.
     One popular application of the laser radar is to make hydrographic measurements from aircraft, where the use of two different frequencies allow simultaneous measurement of the distance from the aircraft to the water's surface and to the sea bottom. This use of laser radar to measure sea depth is known as Lidar Bathymetry.
