In this proposal, Quadrant Engineering seeks SBIR funds to investigate development of an antenna element location measurement system suitable for compensating platform motions in airborne millimeter-wave antenna arrays. During Phase 1 we plan to evaluate three different approaches termed direct, active, and passive. In the direct approach, motion sensors attached to the antenna will be used to d ...

Many simulations environments, particularly those used for training purposes, employ simulated human behavior. To date, users frequently complain that such simulated behavior is not very intelligent and easy to "game" thus reducing the effectiveness of the training. We propose to improve intelligent agent technology through improved techniques for eliciting expert problem solving knowledge on wh ...

The extension of the proposed DUAL LIDAR system from laboratory to aircraft environment will be critically dependent on the performance of the optical bench/structure. This optical bench must support all components (telescope, scanner, lasers, resonator, beam steering optics, and detector) while maintaining critical alignment of the single-mode, heterodyned laser system. Specifically, the struct ...

Capturing the rationale behind decision making in design plays an important role to explain a design, redesign and/or reuse an existing design. Existing design rationale models suffer from the lack of integrating rationale with the design process. The integration is crucial for the domain of software design due to its complexity. A model for design rationale capture and its related knowledge ba ...

This work offers an innovative approach to predicting system behavior (in terms of reliability and performance) based primarily on the structural characteristics of a formal functional specification. The mechanism for process composition is codified in the CSP-to-Stochastic Petri net (CSPN) toll. CSPN supports systematic specification, automatic translation and subsequent augmentation (e.g., fai ...

The success of DoD's thrusts in Global Surveillance and Precision Strike depends critically on the ability to perform Automatic Target Recognition (ATR) and Hostile Target Identification (HTI). The technologies of modeling, sensor data fusion and adaptive intelligent image processing are key to the success of ATR and HTI. An innovative approach to intelligent model-based image processing and tar ...

We propose here new methods for system identification and active feedback control of axial flow compressors under conditions of incipient rotating stall and surge in the presence of inlet distortions. The nonlinear Moore-Greitzer model of rotating stall, which has proven useful for both simulation of rotating stall/surge dynamics of axial compression systems and for control design studies, will b ...

The detection and recognition of man-made objects under foliage conditions requires the use of VHF/UHF ultra-wideband (UWB) radars such as P-3/SAR system developed by ERIM for NAWC/AD and DARPA. At low frequencies and long wavelengths, most of the scatters are in the Rayleigh scattering region and their RCS is low, which enables foliage penetration. However, this also results in a small number o ...

A radical, high performance system design concept for UAV missions is proposed. Its characteristics derive directly from propulsion and power generation capabilities inherent in microturbine technology under development at MIT. The proposed vehicle configurations is an oblate spheroid, giving a high package volume with sufficient fuel capacity for hover duration of about one hour. Thrust from m ...

Standoff detection of chemical and biological agent clouds is extremely important for the protection of US armed forces. We propose a system that will successfully perform stand off detection of both chemical and biological agents using a unique combination of advanced technologies. An imaging Fourier Transform Spectrometer (FTS) will perform the remote detection of chemical agents from an Unman ...
