Dual-Mode Continuous-Wave Ladar and Optical Communications System

Because the data products generated by modern imaging ladar systems are inherently large in information content, there is currently a severe bottleneck in the communications of these products to end users, particularly when full-waveform recovery is desired. Bridger Photonics Inc. proposes to develop a dual-mode laser system capable of performing laser radar imaging as well as high speed free-space optical communications using the same laser source. The system will capitalize on Bridger"s existing ladar technology that can provide, when needed, foliage penetration, Doppler signatures, very high dynamic range, and the highest range resolution available. Bridger will demonstrate that their system architecture is ideally positioned to seamlessly integrate high-speed free-space optical communications as an additional and potentially simultaneous mode of operation without significant alterations to Bridger"s existing system components. To do so, Bridger plans to determine the subsystem design for the free-space optical communication system and model the anticipated system performance. Critical hardware demonstrations will be performed that will highlight the dual-mode operation. Finally, a preliminary Phase II design will be downselected and its costs, performance and feasibility will be determined. A Phase I option will enhance this prototype design to enable a smooth transition to a potential Phase II effort.
