Monopole and dipole antennas have been determined to radiate most efficiently when the size of the antenna is proportional to the frequency being transitted or received, ie.e, one-quarter, one-half or one wavelength. As the operating frequency is varied from that ideal frequency, nulls begin to develolp which threaten the integrity of the communication link. Experience has shown that small excusio ...

The contractor has patented technology for a unique process that directly converts a two-dimensional acoustic disturbance, such as a wave front, into an intensity-mapped visible image in real-time without electronic circuitry; i.e., it is a direct pressure gradient imager. This device can allow a small, battery powered acoustic source to be easily located and ranged using a small flashlight sized ...

The goal of this project is to develop and demonstrate a data fusion system for all active and passive submarine acoustic sensors. The system will perform association of all data associated with a common contact. Associated data will be used to provide improved track estimates and classification performance uncluttered shallow water environments. In Phase I a conceptual design will be developed ...

The overall objective of the proposed research is to develop bistatic detection techniques for shallow water near land warfare operations. The focus of our proposed research is to achieve detection enhancement in environments characterized by dense multipath through application of optimal detection theory coupled with accurate acoustic modeling. The first specific objective is to consider alternat ...

Modern aircraft contain more and more lightweight, but easily damaged, composite structures, with no way to detect in-flight composite delimination or impact damage. Innovative Dynamics (IDI) proposes to address this problem by developing a distributed damage detection system based on embedded piezoelectric actuators/sensors. Prior IDI research showed that an embedded piezoceramic actuator/sensor ...

Significant savings in system life cycle costs can be realized when common Automated Test Systems (ATS) resources are used to meet both system production and field maintenance needs. Additional cost avoidance and quality gains are the result of transferring unit under test (UUT) design data, "lessons learned" gained during manufacturing in-process and system acceptance (sell-off) testing to the ma ...

A fundamental problem in automatic target recognition (ATR) is the overwhelming amount of sensor data which must be processed. Target features are localized within the field-of-view (FOV) of the imaging sensor. Uniformly sampling within the FOV is thuus inappropriate, regions with little or no relevance to the task are samples at the same resolution as key features, occupying valuable signal bandw ...

In this proposal we present a novel approach to aircraft and missile mission and route planning using neural networks. The approach is unique in four aspects: l) it is a proactive planner that looks at the global topographic characteristics of the battlefield environment when generating plans; 2) it uses a cost surface to determine the advantages or disadvantages of moving through an area by integ ...

We propose to conduct a comprehensive feasiblity and assessment study for relevant Navy canopy ejection simulations using an advanced unstructured grid flow solver. The results of the Phase I study will be sued to guide and enhance the development of acomprehensive interactive canopy ejection simulation capability for Navy applications. The study will be conducted to show the feasibility, accura ...
