Abstract :
The merging of lidar and radar in the invention of a hybrid lidar-radar system has been shown to reduce incoherent backscatter clutter by 17 dB, with a corresponding enhancement of underwater target contrast. The success of these laboratory experiments led to the design of a system to be utilized in an ocean experiment. In the past, the main experimental restrictions in the full-scale realization have been the lack of a stable modulated transmitter and a large-area, high-speed optical receiver. Recent advances which have made these two components realizable for use in a hybrid system are detailed
