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 ...

To address the need to mitigate cooperative and noncooperative in-band interference in airborne anti-submarine warfare (ASW) systems, ARiA will develop and demonstrate the feasibility of signal and information processing algorithms for mitigating various types of in-band interference. ARiA will develop and evaluate (1) model-based adaptive signal processing in space, time, and Doppler to mitigate ...

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 ...

To support Navy’s need for novel algorithms using improved energy clustering and association techniques to represent the spatial and Doppler distribution of active-sonar returns to improve active-sonar tracking and classification performance for the AN/SQQ-89A(V)15, ARiA will develop and demonstrate the Next-Generation Clusterer (NGC), a suite of algorithms for feature-augmented contact localiza ...

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 ...
