Ultra-Compact Doppler LIDAR (Light Detection and Ranging) for Unmanned Aerial/Ground Vehicles
Agency / Branch:
DOD / ARMY
The rapid development UAVs and UGVs for the Future Combat System is producing requirements for remote sensing of volumetric winds and wind hazards such as wind shear, gusts, and clear air turbulence for safe and efficient vehicle operation. Mission specific parameters such as aerosol plume detection and tracking, terrain mapping, and helicopter rotor turbulence detection must also be measured. The UAV/UGV operating environment requires any operational sensor to be optimally compact, light-weight, and have low power consumption. In Phase I, CTI: 1) developed requirements, specifications, and a system design for a UAV/UGV coherent Doppler Lidar system, focusing on modularity, compact size, low power consumption, and pulse format flexibility; 2) demonstrated a wide range of laser pulse formats, ranging from short pulses for high-resolution terrain mapping to longer pulses for high-resolution wind sensing; and 3) demonstrated a unique proprietary lidar cavity, enabling construction of small, light-weight, reliable, and rugged transceivers. The agile-pulse laser and the compact cavity architecture form the foundation for the ultra-compact Doppler lidar for UAV/UGV. In Phase II, CTI will: 1) complete the design and perform additional breadboard tests of a prototype sensor based on the Phase I results; and 2) assemble, test, evaluate performance, and deliver an ultra-compact agile-pulse sensor based on this design.
