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.

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 ...

Nuclear batteries have enormous potential as power sources and have many benefits over other types of portable power sources. Nuclear batteries can provide power for at least as long as the isotope half-life and the energetic nature of nuclear radiation means that only a small mass of radioisotope material is required to achieve a high power output and therefore they can have power densities that ...

The goal of this Phase II SBIR is to extract more information from existing submarine acoustic sensors through a highly innovative inter- and intra-sensor correlation algorithmic, in order to provide U.S. submarines with increased acoustic superiority over increasingly quiet adversaries. U.S. adversaries are continuously improving their acoustic quieting technologies through efforts such as marine ...

The ultimate goal of this SBIR effort is to deliver improvements to existing Fleet electronic warfare support systems by using statistical learning techniques to aid in the classification and unique identification of modern radar emitters. Since software-defined and solid-state emitters do not have the analog features traditionally used for classification, we will use more abstract, but well-defin ...

An Interactive Structural Analysis Environment and Management System (iSAMS), designed to support the practice of simulation governance of engineered repairs of metallic and composite aircraft structures, is enhanced, certified and deployed for production deployment. Repairs to modern military aircraft require certified engineering analysis methods. Methods have evolved with the history of airfram ...
