SciFish proposes to utilize Resonance Scattering Theory (RST) modeling to evolve a set of acoustic waveforms that provide optimal material identification while suppressing the affects of clutter and noise. Each waveform will be defined by its bandwidth, pulse width and signal type. Signal types will include FM, Hyperbolic FM, and Phase Shift Key Coded waveforms. An initial set of waveforms will be ...

This Navy SBIR Phase II effort will develop the processing steps required to fabricate high quality periodically poled stoichiometric lithium tantalate (PPSLT) and demonstrate its utility for use in both current and emerging Airborne Laser Mine Detection Systems (ALMDS) by enabling highly efficient laser wavelenth conversion. The proposed optical material will also support the development of shor ...

The VIRGINIA Class submarine employs the Light-Weight Wide Aperture Array (LWWAA) hull-mounted array of fiber-optic hydrophones that requires the use of high performance, narrowband lasers. In this Navy Phase II SBIR effort, a prototype laser for the LWWAA hull-array sensor will be developed using the frequency-stabilized semiconductor laser technology demonstrated during the Phase I effort. The ...

This SBIR Phase I effort will demonstrate the feasibility of a UAV compatible lidar scanner/receiver for use with a high repetition rate, short pulse, multicolor laser transmitter. The system features an electro-optic beam scanner and a fiber optic receiver. The key innovation in this effort is a beam steering device without moving parts which offers high bandwidth, wide scan range, low loss, and ...

The proposed high power green laser source with RF-modulated pulses will enable a new class of remote sensing instruments capable of achieving precise information from environments dominated by backscatter signals. Current remote sensing technologies lack capability to identify and discriminate objects under real-time environmental conditions. A hybrid lidar-radar system consisting of a pulsed l ...

The U.S. Navy is in need of a data collection system for developing a statistical model in terms of probability distribution functions of surface wave slopes. Airborne Technologies, Inc. proposes a unique method of using a dual polarization enhanced sun glint imaging system design that will image sun glints from waves of modest-to-large slopes. We will use optical polarization to enhance the con ...

Alaska Native Technologies, LLC (ANT) proposes to develop a hull-mounted sonar system that would be integrated into the DD(X) HF Mine Avoidance Bow Sonar processing chain to provide search and identification of small objects in the water column ±60° swaths in front of the vessel. The proposed approach will develop a dual-mode broadband sonar system, capable of operating in either wide-beam or n ...

Acoustic sensor systems are the backbone of both anti-submarine (ASW) and mine-countermeasure (MCM) systems. Inadequate knowledge of the acoustic environment, especially in denied areas, results from a lack of survey equipment, funding, and access to areas of tactical interest. Moreover, the acoustic environment can change substantially depending on conditions such as sound speed, water depth, an ...

Currently the E-2C is covered with antennas for VHF/UHF line of sight, UHF satellite communications, L-band and GPS functions. There is a need to condense some of these functions into a single aperture to free up real estate on the aircraft for future additions and cut down on interference between the antennas. Combining these functions into a single multi-function antenna with a weight less than ...

Alaska Native Technologies, LLC proposes to develop a Near-Field Acoustic Holographic Calibration System that would be integrated into a wave piercing Bow Sonar to provide in-port calibration capability for a vessel.
