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. During the Phase I effort, Bridger demonstrated that their 3D imaging system architecture was ideally suited for seamless integration of high-speed free-space optical (FSO) communications. The system will capitalize on Bridgers existing ladar technology that can provide, when needed, foliage penetration, Doppler signatures, very high dynamic range, and the highest range resolution available. During the proposed Phase II effort, Bridger will develop, field test and deliver a fully operational dual-mode 3D imager and FSO communications system. To do so, Bridger will refine its system models and prototype design and then construct the prototype and downlink station. Bridger will field test the device in Corbin, VA out to >2 km. During the second year, Bridger will engineer the FSO subsystem to be robust to strong atmospheric turbulence by integrating advanced coding schemes and multi-aperture transceivers. Finally, the device will be packaged and delivered to the Army in Corbin, VA where final field testing and training will be provided.
