Abstract

A wavelength agile coherent LIDAR system is under development at the Air Force Research Laboratory (AFRL). Coherent lidar has the potential of longer-range sensitivity than conventional direct detection systems. AFRL is conducting risk reduction experiments to address issues involved with coherent LIDAR. Issues include speckle noise inherent to heterodyne detection, robust signal analysis algorithm development, and integration of a wavelength agile laser as the local oscillator to the receiver. The transmitter laser, developed for the LARS program, is a high energy TE CO₂ laser hardened for airborne operations. Performance of the wavelength agile local oscillator laser is presented, and preliminary data from risk reduction experiments.
