Conventional Beamforming (CBF) provides optimum signal detection under ideal ocean conditions (single plane-wave in isotropic, spatially incoherent noise). These conditions never exist in real ocean environments. In order to improve on CBF's performance, Neptune Sciences, Inc. (NSI) has developed… More

Inverse Beamforming (IBF) active acoustic processing and analysis concepts are presented to identify the environmental acoustic parameters that degrade active acoustic sonar performance in shallow water due to time dependent multipath arrivals. A fully coupled normal mode model is proposed to be… More

There exists a need to develop and flight validate a small, lightweight, aerodynamic GPS test instrumentation package to support high speed munitions development. In order to fulfill this need, the Neptune Sciences, Inc. (NSI) team proposes to apply their expertise and experience (as recently… More

Advances in microelectronics, data communication systems and sensor technology have led to the production of relatively small, inexpensive and accurate measuring devices that can be considered expendable. Releasing these compact sensor packages from manned and unmanned aircraft provides the user… More

A significant amount of effort has been applied to the extremely complex littoral environment, particularly in the area of acoustics. The Navy's increasing requirements to operate in shallow water necessitates examination of the Navy's models for prediction of shallow water phenomena. Ambient… More

Not Available The Aegis Team proposes to join two highly innovative elements to solve the research problem presented in Navy Topic N99-170. We will bring together a unique information warfare (IW) wargame/simulation in use at various DOD organizations (e.g., the U.S. Army War College) called… More

Waves and resulting surf play key roles in coastal processes andin affecting many activities including military operations.During successful Phase I research addressing the Office of NavalResearch (ONR) SBIR Topic N98-134,

A long standing problem in oceanography and hydrography is accurate real-time measurement of offshore water levels. The Phase 1 research involved investigating a wide range of recent techniques and technologies, and performing analyses and trade-off studies to evaluate, select, and integrate them… More

Phase I research will be conducted to prove the feasibility of developing a Micro-sized Air-launched Expendable Meteorological Sonde (MAXMS) for both military and research purposes. The proposed research will investigate unique meteorological measurementrequirements and engineering solutions and… More

There is a need for the capability to transmit data from various types of unattended ground based sensors such as biological/chemical, meteorological, audio/video surveillance, communication monitoring/decoying and vehicle/personnel movement sensors. Thesesensors will be precision air deployed using… More

NSI will transition its data fusion algorithms to FDS being developed for a real-time processor called Quiet Interlude (QI), which is currently being sponsored by SPAWAR 05 and PMW-155. This FDS data fusion algorithm will benefit greatly from QI¿¿s fusionof passive sonar, ELINT, and RADINT data. … More

Since the Second World War, increased performance has been acquired by investing heavily in expensive new sensor hardware, at the near exclusion of developing new algorithms and tactics to optimize use of sensors in complex environments. The shift toward threats in just such hostile areas demands a… More

An on-line GIS-oriented management and planning system for four National Marine Sanctuaries will be designed. It will contain static databases of physical, chemical, biological, geological, cultural, historical and archeological information of value to Sanctuary managers. It will link with ongoing… More

The objective is to determine the best algorithmic approach to optimally select unmanned vehicle flight paths that maximize mission success for attached sensors. That involves trade-offs between a) active emissions and passive collections, b) high and low altitudes, c) high and low speeds, d) day… More

The importance of Very Shallow Water (VSW) and the Surf Zone (SZ), VSW/SZ, for littoral operations is well known. Both ocean dynamic conditions and bathymetry may vary significantly in space and time. The harsh SZ environment (mainly due to currents, waves, and surf) makes data collection using… More

SCOUT (Sensor Coordination for Optimal Utilization and Tactics) is a Neptune Sciences, Inc. project that solves a multi-static active sonar optimization problem in an arbitrarily complex environment. SCOUT combines several techniques to identify optimal locations and "ping" times for a discrete set… More
