Award Data

MICA was selected and awarded to ARiA under SBIR Topic AF151-194, technically managed by AFRL/RITB with SAF/AQ-OTI as the sponsor organization. Under prior Phase I and II SBIR efforts ARiA developed, trained, and tested the Machine Interface for Contracting Assistance (MICA). MICA leverages academic and commercial-sector advances in cognitive-computing, deep learning, graph storage, informational ...

All fruits and vegetables generate ethylene.Even low concentrations of ethylene accelerate fruitripening.A process that removes ethylene as it is generated can play a central role in maintainingthe freshness of fruits and vegetables.Hence much effort and significant cost normally go into thecontrol of the atmosphere and temperature to which these fruits and vegetables are exposed largelyto reduce ...

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 ...

In this SBIR effort we will develop an ultra-compact, high-speed, low RIN and high-power transmitter for high-performance RF photonic link applications based on our cutting-edge lithium niobate on insulator (LNOI) modulator. In phase I, we will design, fabricate and characterize a low Vp, push-and-pull LNOI modulator. We will study the optical couplings at the laser/modulator/fiber interfaces to a ...

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 ...

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 ...
