Cargo landing accuracy would greatly improve by precise crosswind measurements on the guided platform - a capability currently not available. CTI proposes to design and demonstrate… More

CTI proposes to develop a ground-based coherent laser radar for satellite vibration measurements. This system will be designed to make measurements of surface vibrations of satellites in orbits of up to 1000 km altitude. The vibration measurements will yield velocity power spectral densities up to 1… More

State-of-the-art wide temporal bandwidth laser radar detectors require high-speed, wide bandwidth, low noise Read Out Integrated Circuits (ROICs) to take advantage of the 1+ GHz bandwidth detectors and exploit a richer set of target signatures at increased spatial resolution. Today's CMOS… More

Future military aircraft will rely heavily on active laser systems to perform functions such as reconnaissance imaging, target designation, communications and directed energy. However, there is significant difficulty in overcoming the effects of atmospheric turbulence and platform vibrations. … More

As active ladar systems become more and more common in missile defense roles, the need for accurate missile signature models increases. Laser radars are currently being pursued for tracking of boosting missiles due to the obvious benefits of clutter rejection and increased precision over passive… More

Single frequency lasers with rapid tuning ability and subsequent active phase noise suppression for sub-1kHz linewidths are key components for coherent laser applications requiring long coherence length local oscillators and Doppler frequency shift compensation. Such applications include airborne… More

USSOCOM requires a real-time wind-profiling sensor to support precision air delivery of PSYOP leaflets and other cargo from the WSADS Leaflet Delivery System (LDS) UAV without exposing personnel to combat loss. The WSADS-LDS platform limits sensor volume to one cubic foot and weight to 30 pounds. … More

There is a need for an Obstacle Avoidance System (OAS) for small unmanned air vehicles (UAVs) to detect fixed obstacles (e.g., trees, buildings, and wires) and proximity to manned aircraft or other UAVs. Small UAVs impose many different constraints, such as flying close to the ground and limited… More
