Helios Remote Sensing Systems, Inc. will develop innovative cognitive software algorithms and techniques for electronic warfare in order to counter highly agile radar emitters. We will define and develop a concept for cognitive Software Algorithms EW techniques for identifying and countering agile threat emitters. We will also develop prototype signal sets that emulate threat emitters. We will dem ...

Within the increasingly contested undersea operational arena, the Navy needs a tactical and competitive advantage in undersea sensing and detection through improved situational awareness with respect to environmental parameters, such as sound speed profile (SSP) and bottom properties, that affect overall submarine sonar sensor performance. Current approaches for enhancing environmental situational ...

This Phase I proposal to Topic N191-022 describes BTech’s approach to develop a smaller diameter version of the ADC MK 4 Mod 1 countermeasure that will fit into a 3-inch diameter form factor. Designs of the electroacoustic transducers and tuning/matching circuits are described that enable low frequency coverage in a smaller diameter vehicle. The proposal draws on BTech’s experience with broadb ...

This Phase I proposal to Topic N191-023 describes BTech’s approach to develop a method to control depth of a 3-inch counter measure to replace legacy system that relies on a propeller. Designs and calculations are presented that support the feasibility of our proposed approach and that it will reduce energy consumption.

A fully planar CTD is proposed that eliminates the need for tubes, vents, and scoops to deliver seawater to the CTD sensor. Additionally, as the planar sensor is directly mounted to the submarines skin, either to the hull or the sail, there is no latency associated with the measurements as with the current configuration. The planar CTD is based upon BHT's patented technology which allows this plan ...

We are developing a deep-learning approach for detecting and classifying torpedo-like threats present in passive sonar data. Interference from merchant ships and biologics often obscure threat signals evident on sonar display surfaces. Experienced sonar operators can distinguish signals of interest (SOIs) such as torpedoes and rogue surface craft from clutter in beam-level displays, but this manua ...

This Phase I proposal to Topic N191-038 describes BTech’s approach to transferring data through a submarine hull with a data capacity in excess of 10k bit/sec (bps) using piezoelectric ultrasonic transducers. Some of the communication techniques include signaling to increase data packet detection at lower power levels. The Phase I baseline design of the signal schemes and the transducer system w ...

The aircraft carrier Cross Deck Pendant (CDP) is vital to the operation of Naval Aviation. Their design, construction and operational use have been developed for many decades through a combination of engineering and operational experience. Currently in process changes to aircraft landing control systems and the introduction of unmanned aircraft the fleet air wings will introduce changes to the CDP ...

Helios Remote Sensing Systems proposes to develop and demonstrate a maritime Inverse Synthetic Aperture Radar (ISAR) imaging algorithm that is robust to electronic attack (EA). We will develop an innovative maritime ISAR imaging algorithm that is robust to EA for operation in highly contested environments. We will develop a novel ISAR framework and imaging algorithm that leverages the physics of r ...

Field programmable gate arrays (FPGAs) are becoming increasingly critical components in advanced electronic systems. However, limited research has been applied to identifying critical vulnerabilities that could be present in the designs deployed on these FPGAs. The risk is further increased by the use of 3rd party intellectual property in many designs.GrammaTech is proposing to develop a Trust ver ...
