During Phase I, HMI concepts were developed to facilitate work load sharing, collaboration, and interoperability of tools and displays. Attention was given to simplicity and efficiency to reduce the number of menus and button clicks, eliminate windows, and simplify controls to be more intuitive.In Phase II the conceptual displays will be developed into a fully functioning prototype and integrated ...

This project involves the development of hull mounted acoustic motion (accelerometer) sensor with increased sensitivity (+6dB), greater stability, and low cost for hull mounted sonar arrays. Investigations and developments of sensors without and with preamplifiers is considered.

The objective of the proposal is to reduce the cost of fabrication of sapphire optical hyper-hemispheres for submarine masts. Due to the nature of sapphire, deriving complex geometries from grown boules using current conventional fabrication techniques is one of the major contributors to cost. Removing excess material requires long diamond grinding cycles. New advances in ultrasonics have been inc ...

A system to covertly communicate in underwater acoustic shallow water environment for mine countermeasure is described. Techniques for LPD and directional communication are suggested.

Geometrically constrained underwater environments abrogate the simplifying acoustic modeling assumption that energy can be modeled in a two-dimensional vertical plane. In these environments, current tools to perform navigation and passive and/or active sonar mission planning are inadequate. Furthermore, channel complexity makes it difficult to model acoustic communications. HRC proposes to upgrade ...

This proposal considers technologies and methods to realize low probability of detection (LPD) acoustic modem systems using low SNR techniques, camouflage techniques, and directionality to enhance covertness. Phase I baseline designs will be recommended based on past and new work of the contractor

The focus of Phase II shall be to demonstrate the feasibility of alternative seaming technologies for military use. Building on the work in Phase I and the Phase I Option, the NWU Parka Type I shall be the demonstration model for comparison purposes of technology advances. This high cost garment utilizes both traditional stitching and complex seam sealing techniques, and is an excellent example fo ...

The primary objective of this effort will be the development of a software toolset capable of modeling dynamic two-phase flow systems for controls development and optimization. The toolset will be comprised of a variety of components related to two-phase flow systems with user interfaces to parameterize the component models and a variety of supporting tools for operating the models and analyzing r ...

This project will focus on the combination of high performance, reconfigurable microwave and millimeter wave filters, and advances spectrum sensing hardware to produce a digital radar warning receiver capable of operating in a dense RF pulse environment. The reconfigurable microwave filters will allow the sensitive receiver to operate in the presence of large signals while maintaining the sensitiv ...

A critical element in higher power systems such as T/R modules, communication transmitters, and EW modules, is power combiners. To obtain the necessary output power, systems typically require multiple combined power amplifiers. Various options are available, however, the trade-offs between options must be fully understood. Couplers based on planar structures or 2.5 dimensional designs are readily ...
