The ultimate purpose of the proposed R&D is to develop and demonstrate an innovative software development environment which supports the engineering, analysis, development, test, maintenance, and reuse of software for embedded, heterogeneous, real-time systems. The proposed approach is innovative in two respects: (1) it is based on the integration of two best-of-breed environments, ObjecTime/ROOM ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

Astralux will develop IV-II-VI compound semiconductors by synthesizing compounds and characterizing their properties as a function of the deposition parameters. The material will be a combination of lattice-matched semiconductors that will be generated as alloys and superlattices. Electronic and optical properties will vary by adjusting the composition. The II-VI compound semiconductor has optical ...

Sensitive operation of passive sensors in a radiation environment requires a means to eliminate the signals caused by ionizing radiation. Black Forest Engineering proposes a signal processing technique to delete these gamma-spike signals that can be integrated into each unit cell of an infrared planar hybrid sensor chip assembly. This technique is applicable to both scanning and staring systems wi ...

A NOVEL LIQUID CRYSTAL BEAM IS PROPOSED. THE ACTIVE MATERIAL PRODUCES ANALOG PHASE MODULATION (NEARLY 2 PI) WITH A SUB-MICRON LAYER, SWITCHING AT MICROSECONDS. TO ACHIEVE LARGE STEER ANGLES AND HIGH DIFFRACTION EFFICIENCY, HIGH SPATIAL FREQUENCY STRUCTURES WITH ANALOG PHASE ARE REQUIRED. THE NEMATIC MATERIALS CURRENTLY USED FOR SUCH DEVICES EXHIBIT SLOW RESPONSE TIMES, AND LIMITED RESOLUTION. WHIL ...

Data Fusion Corporation and Space Computer Corporation proposes a distributed-sensor version of the track-before-detect method for detecting faint moving objects in noisy, cluttered images. Track-before-detect combines multiple images from a single sensor to detect a moving object's trajectory as a whole, versus detecting single snapshots. Fusion of distributed sensor observations improves detecta ...

Digital Wave Corporation proposed to develop a novel nondestructive testing (NDT) system for high speed acquisition and analysis of wide band acoustic emission (AE) waveforms. The system will provide the capability to detect, identify and locate crack growth in loaded steel structures. This system will incorporate the new high fidelity sensor developed by the Federal Highway Administration and a ...
