Not Available A new approach to significantly increasing the level of monolithic integration of InP based photonic integrated circuits for RF applications is the subject of this proposed Phase I program. The method is based on a vertically coupled twin wave guide design that has already been successfully used to fabricate lasers and amplifiers. The fabrication process requires no epitaxial re-g ...

Not Available Existing approaches to the detection of vehicles from SAR imagery are handicapped by a high false alarm rate, especially when used in high clutter environments such as urban areas and forested regions. In this Phase I proposal. Image Corp, Inc. proposes a system for SAR-based vehicle detection that makes extensive use of contextual information derived from the SAR image itself. Mu ...

The Defense Modeling and Simulation Office (DMSO) has developed the High Level Architecture (HLA) as one of the principle components of a DoD-wide Common Technical Framework for modeling and simulation (M&S). Unlike previous distributed simulation technologies such as DIS and SIMNET, HLA provides federation developers, via the Object Model Template (OMT), the means to define the structure and for ...

A new liquid crystal based detector (acousto-optic sensor) will be developed for operation at frequencies below 500kHkz. The superior acoustic detection sensitivity of the sensor will be demonstrated and its feasibility for providing efficient and cost-effective means of acousto-optic image conversion in underwater acoustic imaging systems will be established.

Breathable release coatings that can withstand processing conditions up to 750F are needed for use on ceramic tooling. In situ removal of volatiles in solvent-based composite processing is a critical issue that will enable production of high quality parts at lower cost per part. Current release coatings meet neither the temperature nor the solvent transport requirements of solvent-based composit ...

The development of a remarkable Ti3SiC2 material for use in ceramic matrix composite (CMC) fiber coatings and matrix laminates is proposed. This material possesses a myriad of favorable properties for high temperature structural applications - demonstrating machinability, strength, ductility, oxidation resistance and thermal shock resistance never before observed in a single phase material. Prop ...

We propose a radically innovative approach to the problem of multiple access communication which promises to revolutionize the modern communication industry by dramatically increasing network throughput. Our approach is based upon two major novel components: (i) hybrid time-frequency allication of communication channel resources, and(ii) non-orthogonal, i.e., overlaping, multiplexed signals. Toge ...

The adaptive single user receiver invented at AF LAB has been shown to suppress multiuser and certain forms of narrow-band interference in adecision directed mode during the entire transmission, without requiring knowledge of other users spreading codes, timing or phase information in direct-sequence proposal, we investigate the use of our single user receiver for secure communications as required ...

The final prototype of the Microcircuit Board Repair apparatus will be capable of laying down or lifting metal strips with micrometer dimensions. Under real time computer control, the translation stages will be fully automated or manually controlled. The end user will monitor the process in real time using a camera attached with the source. Laying down the metal lines will be done using Laser C ...
