Design of a novel digital signal processing (DSP) radiometer system is proposed, which combines a low-noise, high stability radio frequency (RF) down-converter, a high speed digitizer with a deep buffer memory, and a personal computer running an innovative DSP software known as X-Midas. X-Midas allows the user to construct a software DSP system by selecting functional blocks through a user-friend ...

Propulsion system components are being exposed to increased thermal and aerodynamic loads. Active stabilization of these components is considered one of the key technologies required to enhance the oeprability of gas turbine engines. Recently there have been numerous successful demonstration of active control to alleviate compressor surge and rotating stall. Almost all of these active surge/stall ...

Metal additives to explosive formulations are commonly used in high energy military and commercial explosives, solid fuel rocket propellants and military and commercial pyrotechnics. Aluminum metal is a stable low cost fuel that is typically used in the form of powder or flake. In high energy systems the energy of the balst and the velocity of the detonation wavefront can be limited by the utiliza ...

Photorefractive materials promise to enable dynamic holography and erasable high density data storage for future information technologies. This project will develop and demonstrate a holographic data storage technology using novel photorefractive polymers with electro-optic (EO) coefficients and bandwidths that are significantly superior than LiNbO3. An important advantage of these polymers is tha ...

Hydrazine is a highly toxic compound that is widely used as a rocket fuel in U.S. space programs. Since very low concentrations of hydrazine are considered hazardous, there is need for sensors that are robust, cheap, sensitive and selective. Sigma Labs proposes a low cost manufacturing method for fiber optic sensors with reactive, colorimetric claddings. The coating process is characterized by ...
