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… More

The United States Coast Guard`s homeland security mission includes providing security for 361 ports and 95,000 miles of US Coastline. This coastline is susceptible to both criminal and terrorist attack. Waterside facilities and critical infrastructure are especially vulnerable to attack from on or… More

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… More

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… More

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.

Alaska Native Technologies (ANT) and Johns Hopkins University-Applied Physics Lab (JHU-APL) have teamed to present an innovative, solution to the acoustic inversion sensor problem by combining a new, cost effective, high gain, broadband array (JHU, sponsored by ONR Code 32) with a new UUV (glider,… More

The proposed MFA is a complex, highly integrated architecture comprising a number of distinct radiating structures in a very compact package. The antenna design centers around a pair of conical radiators, which are DC (Direct Current) connected to the chassis/fuselage of the aircraft, as required in… More

ANT has recently developed a similar recovery system for our own autonomous vehicle. ANT's current system lifts a vehicle of lighter negative buoyancy (~64lbs rather than 200 lbs). The system is also designed to operate at less maximum depth (200 m, rather than 900 ft). These changes will… More
