High Speed Optical Transmitter and Receiver

Abstract

This proposal concerns component development for a novel hybrid lidar-radar system for underwater surveillance. Computer simulations and laboratory measurements of pulsed lidar revealed a 17 dB suppression of the water backscatter signal (clutter) and corresponding target contrast enhancement. Preliminary ocean experiments have confirmed the potential of pulsed lidar to be a superior detection mechanism for underwater surveillance. The next step in the evolution of this novel technique is the improvement of the key components of the measurement system: the microwave modulated pulsed laser sources and high speed, large area photodetectors. These components are novel and with minor modifications are applicable in communications and other areas of current interest.
