Directed electromagnetic (RF, microwave and millimeter wave) energy offers unique and flexible options for non-lethal weapons, but the technology for these systems needs to achieve smaller and lighter packaging. Of particular interest are the Multi-frequency RF Vehicle Stopper at L-Band and the Active Denial Array at W-Band. The antennas currently employed for these systems are large reflectors th ...

n this Phase I effort, FIRST RF will develop and evaluate concepts enabling highly directive multi-beam TCDL communications using phased arrays integrated on the Fire Scout UAV platform. Phased array systems allow for dynamic beam steering with graceful degradation. The use of multibeam arrays will allow the Fire Scout and other UAV platforms to augment fleet communications, supporting information ...

Applied Radar proposes to develop a high-gain low cost, size, power and weight (low-CSWAP) tactical common data link (TCDL) antenna for the Firescout and Predator UAVs. The improved TCDL antenna will support 6 or more nodes of high-gain full-duplex communication at 21.42 MBPS in a star network configuration with 360 degree coverage out to 110 nm slant range. In Phase 1, we will design, fabricate a ...

The personal protective equipment (PPE) worn by firefighters protects them against burns and hazardous environments. This equipment works so well that they may not notice that their environment has become so hot that is no longer safe. Although current thermal sensor technologies (generally built in to Personal Alert Safety System (PASS) units) can trigger an alarm when the temperature is too hig ...

Oceanic refractivity gradients induce operational and security concerns of naval operations. Continuous passive characterization of refractive effects upon visble, IR, and radio/RADAR electromagnetic propagation through passive relatively inexpensive multiband IR camera observations is enabled with the apparatus and methods proposed herein.

Electric ships and other Naval applications employing batteries (and ultracapacitors) for energy storage need a universal battery management system (BMS) that can diagnose device degradation and ensure safe operation. The Navy currently faces a difficult situation; where each energy storage device has a dedicated BMS, often with limited diagnostic abilities. TDA will develop a modular BMS with uni ...

The Navy Ohio Replacement Ballistic Missile Submarine Program is a major endeavor aiming at designing and building a new class of 12 ballistic missile submarines (SSBNs) to replace the current force of SSBNs. Current Ohio-Class SSBNs are armed with Trident ballistic missiles or Tomahawk missiles if converted to guided missile submarines (SSGNs). These missiles are launched from vertical launch tub ...

BTech proposes the design and development of a low-profile, broadband, shear-mode piezocrystal acoustic transducer for deep submergence applications. The Phase I effort considers evaluation of design variants of shear mode transducers with increased pressure operation/tolerance and tradeoffs associated with the same. Design feasibility is supported with calculations of expected performance and whe ...

Under the Phase I SBIR effort, we designed a Submersible GPS Enhancement and Playback System (SGEPS) to allow processing of the GPS signals after a submarine has submerged to reduce the time spent on surface for covert operations. This uses a Digital Storage Receiver (DSR) for capturing the GPS RF signals in the surface and a SAASM GPS receiver for the signal playback and processing after the subm ...

The Navy has expressed interest in shipboard high-temperature superconducting (HTS) cable systems for power transmission and degaussing purposes. The practical application of such cable systems require flexible superconducting cables and cable connectors that allow for a quick and reliable installation into, or removal from, its pre-installed cryostat. Advanced Conductor Technologies LLC (ACT) of ...
