Although satellite-based SAR is sensitive enough to pick up the modulation effects of internal waves, the signal-to-noise ratio (SNR) of th-Ls observable is believed to be to() low to afford detection of enemy sukuiarines . Adaptive Software prolses that with a new interpretation of singular value decomposition, the SNR can be improved enough to allow automated detection of sukfmrine paths. While ...

Standard U.S. Navy fiber optic assemblies require that the fiber be bonded to the connector using an adhesive that is labor intensive and heat controlled (MIL-A-24792). Advanced Material Systems (AMS) proposes a study that could solve this problem through the development of an adhesive system that would cure at room temperature in less that 3 minutes and yet meet all of the in-service req ...

1 New concepts in optical computing and optical interconnects require hardware developments of generic, compact, multi-element LED source array. A two dementional array of individually-addressable Light-emitting Diode optical emitters will be developed. An innovative CVD/LPE heteropitaxy technique will be employed for the monolithic integration of high-speed-surface-emitting AlGaAs/GaAs LEDs on si ...

THE FEASIBILITY STUDY INCLUDES R&D TASKS TO INVESTIGATE THE FOLLOWING: A) WORKPIECE CLASSIFICATION; B) WORKPIECE LOCATION AND ORIENTATION, AND C) WORKPIECE SURFACE CONDITION. THESE TASKS INCLUDES PREPROCESSING OF REAL-TIME VIDEO DATA FROM A SPECIAL 3-D VISION SYSTEM, AND APPLICATIONS OF ADVANCED COMPUTER VISION METHODOLOGIES TO CARRY OUT THE INVESTIGATION OF A), B), AND C).

The objective of the proposed program is to design, using graphite fiber fabric, high thermal conductivity thermal doubler/electronic component bonds that can be debonded easily at low temperatures for repair. The design and selection of materials for these bonds will be guided by computer modeling and analysis work. The thermal performance of polymer bond materials reinforced with high thermal c ...

Recent trends in submarine design indicate the need for-locating more electrical components, such as propulsion motors and actuators, outside the pressure hull. As a result, there is a need for electrical hull penetrators/connectors which can transfer high currents or high voltages through the submarine's pressure hull. We propose to review the capabilities and limitations of existing penetrator/ ...

Enemy forces can be crippled quickly at the beginning of a war by separating the enemies command and control structure from its combat forces and other elements of its defensive network. A false target generator has the potential to saturate or tie up an enemies air defense net and increase survivability of our own airborne assets. An unmanned aerial vehicle (UAV) is an optimum candidate for a dec ...

A NOVEL TECHNIQUE (PATENT IN APPLICATION) IS PROPOSED FOR THE NON-DESTRUCTIVE MEASUREMENT OF LONGITUDINAL STRESSES IN RAIL WHICH MAKE USE OF TWO PHENOMENA KNOWN AS (1) MAGNE TOSTRICTION AND (2) SKIN EFFECT. MAGNETOSTRICTION IS EXHIBITED BY FERROMAGNETIC MATERIALS SUCH AS RAIL STEELS AND GIVES RISE TO A CHANGE IN THE MAGNETIC PERMEABILITY WITH APPLIED STRESS. THE SKIN EFFECT DETERMINES THE DISTRIBU ...

The complexity of modern military systems makes it critical that degraded operators be identified prior to going on duty. Current readiness to perform tests primarily utilize off-line behavioral techniques to identify such operators. The present proposal details two separate but related developments which will provide DOD with both a near-term and longer-term approach to this area. First, a por ...
