Phase 2 SBIR

Agency: Navy
Topic: N03-146
Budget: 09/27/04 - 09/28/06

In Phase I Robust Towed Array Beamforming (RTAB) work, Applied Hydro-Acoustics Research, Inc. (AHA) developed and tested several candidate algorithms, including a data-adaptive "Hole-Filling" algorithm, that recover losses of acoustic performance resulting from acoustic channels failures. With SURTASS TwinLine-R sea-test data we have shown a 2 t...

Phase 1 SBIR

Agency: Navy
Topic: N04-071
Budget: 05/06/04 - 11/06/04

Reducing reverberation noise, and increasing resolution drive the ability to detect, and classify underwater mines in a shallow littoral environment. This proposal addresses the problem with an analysis of reverberation noise from recorded sea tests, adaptive beamforming (ABF), and adaptive direction of arrival estimation (ADOA). In the reverber...

Phase 2 SBIR

Agency: Navy
Topic: N02-182
Budget: 03/22/04 - 03/22/06

The objectives of this research are to design and develop a software prototype of a realistic ocean simulation system primarily to support development of environmental sensors through more precise evaluation of sensor design alternatives. This simulation system, the Environmental Sensor Simulation System (ESSS), must accurately represent the oc...

Phase 2 SBIR

Agency: Navy
Topic: N02-152
Budget: 03/17/04 - 03/17/06

The objective of this research is to develop alternatives for a total planning system solution for use of environmental sensor data for the tactical ASW warfighter. This software will be used for pre-flight planning to evaluate alternatives and develop effective tactical search plans based on available environmental data and threat data, to p...

Phase 1 SBIR

Agency: Navy
Topic: N03-146
Budget: 08/12/03 - 02/12/04

Even when built to exacting standards, towed arrays invariably suffer acoustic sensor failures. A relatively small number of sensors can have large negative impact on beamformer side-lobe levels. This SBIR program will develop, implement, and integrate a towed array beamformer shading algorithm that provides robust performance as hydrophones fa...

Phase 2 SBIR

Agency: Navy
Topic: N01-014
Budget: 03/24/03 - 03/24/05

The objectives of this research are to fully design and develop a prototype of an environmental impact assessment and mitigation software suite, focusing on the impact of active acoustic emissions on marine mammals. This software will be: web-enabled, cross-platform capable, and be applicable throughout the life cycle of active source programs...

Phase 1 SBIR

Agency: Navy
Topic: N02-152
Budget: 11/21/02 - 05/20/03

The objective of this research is to research alternatives of a total planning system solution for use of environmental sensor data for the tactical ASW warfighter. The software will plan an integrated deployment strategy for both environmental and tactical sensors prior to takeoff. It will run rapidly and take into account trade-offs of using...

Phase 1 SBIR

Agency: Navy
Topic: N02-182
Budget: 11/08/02 - 05/07/03

The objective of this research is to produce an environmental sensor simulation system (ESSS) that will support advanced research and development for ASW. Efforts are underway to design new environmental sensors that will enable accurate, timely measurement of the ocean environment, especially for the shallow littoral regions where the environm...

Phase 2 SBIR

Agency: Navy
Topic: N01-127
Budget: 09/06/02 - 09/06/04

The next generation USW combat system will implement improved active/passive sonar processing in a COTS architecture. Shipboard sensors include radar, hull array, towed array, and sonobuoys. The sonar analyst must efficiently manage a huge increase in information to realize the full potential of future undersea warfare sensors. Since ...

Phase 1 SBIR

Agency: Navy
Topic: N01-127
Budget: 11/26/01 - 10/10/02

The objective of this proposed research is to define a USW tactical data fusion architecture and develop a fusion algorithm baseline that can continue to mature through an incremental technology and software build process. Phase 1 program emphasis will be placed on data fusion algorithm assessments and architecture definition for the USW combat ...
