Accurate Automation Corporation (AAC) has developed a new artificial neural network processor (NNP) based upon a sparse Multiple Instruction Multiple Data (MIMD) structure which is ideally suited for Electronic Warfare (EW) applications. The proposed research will investigate the use of the AAC NNP for EW applications such as emitter identification which is used in ELINT, ESM, and RWR receivers. T ...

We propose to develop an automated Pilot Induced Oscillation (PIO) detection and compensation system. This will use artificial neural networks to increase speed and the envelope of operation. PIO is caused when a pilot overcompensates during a "high gain" task such as landing, takeoff, refueling, dropping stores, or tracking. It can also be caused by inefficiencies in the inner loop controllers ...

The feasibility of fabricating hypersonic aircraft components from metastable Beta Titanium alloy (Beta 21S) will be investigated. Techniques for the fabrication of the leading edges, inlet, and nozzle areas of a hypersonic (Mach 4-5) testbed aircraft from Beta 21S will be selected and preliminary drawings, specifications, and test procedures for these components will be developed.

Holloman AFB rocket sled requirements for computing the aeroheating and structural temperature effects thereof exceed the capabilities of available aeroheating methods in that accounting for shock impingement heating, real-gas, or non-air effects as needed for the sled application may be absent from these methods. In this SBIR Phase I effort an approach is proposed which will modify a flow code s ...

A methodology is proposed for introducing the capability of modeling active MMICs into the industry-standard three dimensional electromagnetic field simulator High Frequency Structure Simulator (HFSS) and Maxwell SI Eminence. The first objective of the proposed work is to evaluate the existing capabilities of HFSS/Eminence for characterizing the passive three dimensional interconnect problems as ...

Currently, most antenna array designs are mechanically steered. However, as demand for higher performance antennas increases, an electronic replacement for the mechanical system becomes necessary. An alternative that may prove to be more cost effective is to use ferrite patch antennas as the elements in the array. The antenna's radiation characteristics are controlled by the direction and magni ...

We propose a unique GaN-Al(sub x)Ga(sub 1-x)N heterojunction based CCD for imaging in the ultraviolet (wavelengths less than 365 nm). Our proposed device will be solid state, TTL compatible and in it's final configuration solar blind. The Phase I program is aimed at establishing the technical feasibility of our device concept. Our proposed CCD is in essence a GaN-AlGaN gated photoconductor with ...

This proposal describes new low cost, low risk semiconductor-based approaches to fuze trigger circuit technology. These innovative approaches build on the promising new technology platform developed by ARIA as part of earlier SBIR research. ARIA's technology platform, initially developed for driving extremely high speed (400 picosecond rise time), high peak current pulses (400A) through laser di ...

A concept for intelligent, multimedia computer-based training systems integrating intelligent agents with eye tracking and speech (ScanEval) is presented as a means of developing training systems that are more responsive, engaging, and motivating to trainees than current systems relying on more traditional user interface and pedagogical sequencing mechanisms. It is argued, based on published rese ...
