NASA has a requirement for a large-area, high-quantum-efficiency, high-throughput optical receiver for ground-, air-, and space-based LIDAR systems. A radiation-hardened direct detection analog LIDAR receiver will be developed to address this need in the proposed STTR program. The rad-hard LIDAR receiver will be based upon a high gain (M > 1000), low excess noise (k ~ 0.02) InGaAs APD technology w ...

Fault-Tolerant Control (FTC) is an emerging area of engineering and scientific research that integrates prognostics, health management concepts and intelligent control. Impact Technologies and the Georgia Institute of Technology, propose to build off of a strong foundation in fault-tolerant control (FTC) research performed with NASA in past years to mature the applicability of this technology and ...

The ability to quickly and reliably simulate high-speed flows over a wide range of geometrically complex configurations is critical to many of NASA's missions. Advances in CFD methods and parallel computing have provided NASA the core flow solvers to perform these simulations. However, the ease of use of these flow solvers and the reliability of the results obtained are a strong function of t ...

Impact Technologies, in collaboration with Georgia Institute of Technology, proposes to develop and demonstrate innovative technologies to integrate prognostics into Automated Contingency Management (ACM) for advanced aircraft controls. Without consideration of prognostic information, the traditional reactive fault tolerant control approaches may fail to provide optimal fault mitigation/accommodat ...

Reconfigurable antennas are attractive for remote sensing, surveillance and communications, since they enable changes in operating frequency and / or radiation pattern, resulting in high-bandwidth antenna systems, with broad areas of coverage. Additional functionality would be achieved by integrating: control, processing, and communications directly onto the antenna substrate; MEMS sensors into th ...

This research focuses on fully developing energy density sensors that will yield a significant benefit both for measurements of interest to NASA, as well as for general acoustic measurements. Previous research has developed prototype energy density sensors. The Phase I research focused on developing effective calibration techniques for these probes, testing and validating the probes to identify th ...
