OTI proposes to identify, research, prioritize, select and prove concept feasibility of techniques for testing concurrent, real-time, distributed, large-scale software during Phase I. A prototype proof-of-principle will be build during Phase II of this program by integrating test techniques selected during Phase I of this SBIR into OTI's existing SADCA test environment.

The project objective is to examine descrimination techniques that can be implemented without modifying EWR hardware or software. Pattern recognition techniques is one approach. With approximately 100 seconds of Radar Cross Section (RCS) vs. time data, a trained observer can generally discriminate between Reentry Vehicle (RV) and tank like signatures when the data is displayed over time because th ...

GROWTH OF OEDERED Ga(1-x)In(x)P ON GaAs, AS A THIN FILM MATERIAL SHOWING VERY STRONG NONLINEAR OPTICAL (nlo) EFFECTS, WILL BE ACCOMPLISHED BY METALORGANIC CHEMICAL VAPOR DEPOSITION (MOCVD). IT IS WELL KNOWN THAT MOCVD-GROWN Ga(1-x)In(x)P DISPLAYS VERY STRONG ORDERING OF THE Ga- AND In-SUBLATTICES, AND THAT DEGREE OF ORDERING IS CONTROLLED BY GROWTH PARAMETERS. STRONG ORDERING SHOULD LEAD TO THE LA ...

Spire proposes to design and fabricate In(-1-x)Tl(-x)Sb long-wavelength (8 to 12 micrometers) infrared detectors. Theoretical calculations predict that InTlSb offers many potential advantages over HgCdTe and III-V quantum well infrared photodetectors (QWIP). Its higher mechanical strength and better compositional uniformity promise improved focal plane array performance and yield. Also, since it i ...

SPIRE PROPOSES TO DEVELOP FOR THE FIRST TIME DEPOSITION TECHNIQUES FOR CREATING THIN FILMS OF ZnGeN(2) OF HIGH CRYSTALLINE PERFECTION TO SERVE AS THE BASE IN HIGH TEMPERATURE HETEROJUNCTION TRANSISTORS. THE FINAL TRANSISTOR STRUCTURE, TO BE DEMONSTRATED IN PHASE II, WILL RELY ON GALLIUM NITRIDE (GaN) AS THE EMITTER AND COLLECTOR SECTIONS. ZnGeN(2) IS AN EXCELLENT CANDIDATE FOR SERVING AS THE TRANS ...

We propose to use the 'double-crucible' technique to grow semi-insulating gallium arsenide crystals which are of uniform stoichiometric composition from seed to tail, and are free from arsenic precipitaties. The nature of the phase diagram suggests that this approach should be very effective in GaAs, and the Principal Investigator has already established to use of the double crucible method in Liq ...

THE ABILITY TO LIFT HEAT FROM A SELECTED PORTION OF THE SPACECRAFT IS REQUIRED IN A NUMBER OF THERMAL MANAGEMENT TASKS FOR SPACED BASED SENSOR AND WEAPON SYSTEMS. THE PROPOSED EFFORT WILL DEVELOP THE THEORETICAL AND ANALYTICAL FRAMEWORK TO ASSESS THE UTILITY AND FEASIBILITY OF A HOT PISTON PULSE TUBE VUILLEUMIER REFRIGERATOR. THE EFFORT WILL IDENTIFY A BASELINE APPLICATION FOR THE PROPOSED CONCEPT ...

ASPEN SYSTEMS PROPOSES AN INNOVATIVE APPARATUS FOR REMOTE MEASUREMENT OF CLOUD AND FOG PARAMETERS, SUCH AS WATER CONTENT. THIS LIDAR APPARATUS USES STATE-OF-THE-ART LASER TECHNOLOGY TO MEASURE THE PROPERTIES OF A CLOUD OR FOG (CONSTITUENT, WATER DROPLET SIZE AND CONCENTRATION) REGARDLESS OF AMBIENT LIGHT CONDITIONS (DAY OR NIGHT) OR LOCATION OF DEPLOYMENT (GROUND BASED OR AIRBORNE). THE PROPOSED L ...

ASPEN SYSTEMS PROPOSES TO DEVELOP HIGH DIECTRIC CONSTANT (K) SELENIUM POLYMERS TO MEET THE DESIGN OBJECTIVES OF HIGH ENERGY DENSITY CAPACITORS (HEDC) FOR ENERGY STORAGE IN PULSED POWER SYSTEMS (15 TO 45 MJ/kg). IN THE PROPOSED PHASE I WEL WILL SYNTHESIZE HIGHLY PROCESSABLE, Se BASED POLYMERS AND FABRICATE SAMPLES OF FILM FOR DIELECTRIC ANALYSIS. INITIAL, RIGOROUS CALCULATIONS HAVE BEEN PERFORMED B ...

DYNETICS PROPOSES A NOVEL PROCESSING TECHNIQUE FOR INCREASING THE RANGE RESOLUTION CAPABILITY OF A LARGE CLASS OF RADARS. THIS TECHNIQUE, LINEAR FREQUENCY MODULATION ENVELOPE PROCESSING (LFMEP), ALLOWS RANGE RESOLUTION FOR LFM SIGNALS THAT IS NOT LIMITED IN THE USUAL WAY BY THE WAVEFORM'S BANDWIDTH. THEORETICALLY, THE TECHNIQUE IS ABLE TO RESOLVE TWO TARGETS SEPARATED BY AS LITTLE AS 10 WAVELENGHT ...
