In Phase II, Daniel H. Wagner Associates will build a full-scale prototype Multi-Sensor Data Fusion System (MSDFS) using a modular approach to allow for a straightforward transition of the innovative MSDFS technologies into the DD(X)/Open Architecture Track Management (OATM) architecture and also into other Navy combat and command and control systems, especially Anti-Submarine Warfare (ASW) and To ...

Propagation Research Associates, Inc., (PRA) proposes to develop a software/hardware-in-the-loop (S/HWIL) capability that will implement the PRA Fast Algorithms for State Estimation (FASE) in a real-time environment. PRA developed a maximum likelihood estimator and a smoothed iterated filter to reduce filter transients. The PRA S/HWIL will provide a unique capability to 1) evaluate the performance ...

Effective Naval warfare depends on accurate estimates of sensor performance in complex environments, which provides a force multiplier by allowing friendly forces to optimize their tactics while avoiding counterdetection. The shift in emphasis from open ocean to littoral operations has increased the demands on models of sonar performance because data must be sampled at an order-of-magnitude finer ...

This proposal addresses the development and use of lightweight, low thermal-capacity reformable tooling materials for high-temperature composite processing evaluation, parts prototyping, trial production and full-rate production of PMC engine components. The weight-saving promise of high-temperature polymer matrix composites (PMCs) for engine components is offset by the very high costs of parts m ...

"ACIT has studied a remotely addressed strain detection system consisting of a passive embedded sensor and a handheld detector, used in either a stationary or portable mode. This Proposal will demonstrate the utility of the strain detection system forspecific advanced composite materials used in aerospace vehicles, fulfilling a critical need to assess the mission capability of advanced composites ...

"A study is proposed in which the performance of an underwater acoustic vector sensor (AVS) containing conventional piezoelectric transducers is compared with that of an AVS containing single crystal piezoelectric transducers. An acoustic vector sensor isa device that measures three orthogonal components of the acoustic particle velocity in conjunction with the acoustic pressure at a single point ...

"Acoustech proposes a Phase I study to develop an acoustic dyadic sensor using piezoelectric single crystals. The study combines theoretical and numerical modeling along with experimental data obtained from a pre-prototype unit to assess the feasibility ofdeveloping a full scale unit during Phase II for a surveillance application. Greater sensor directivity in a comparable or smaller sized packag ...

This project will investigate candidate space-time coding schemes to be incorporated in a multiple-input multiple output two-way communication system that operates within an urban warfare environment. The main objective is to increase channel capacity to achieve high-quality video transmission using narrow signal bandwidths, typically deployed for voice channels. The investigation will determine t ...

An aqueous-based finish (sizing) was developed in Phase I to improve the carbon/vinyl ester interfacial bond. The finish is composed of a reactive coupling agent, a low viscosity vinyl ester resin, a free radical inhibitor, and a surfactant. The reactive finishes substantially improved the carbon/vinyl ester interface compared to unsized or FOE sized materials. Failure mode analysis shows that ...

New high-temperature sizings are needed to improve the properties and durability of carbon/polyimide composites. Compatibility with weaving and braiding operations and improved wetting during prepregging or resin infusing polyimide resin is also needed. Achieving these characteristics will result in reducing life cycle costs for jet engine composites through better property translation, reduced ...
