In the Phase I STTR, N08-T029 “Novel Fiber Optic Methods for Sensing Shape, Orientation and/or Heading of Undersea Arrays and Tethers” a concept was developed for a fiber optic sensing array and shape reconstruction algorithm to be used for situation awareness of flexible undersea cable structures. Undersea cable structures are deployed in environments unsuitable for direct in-situ observation ...

The objectives for this Phase II effort follow logically from the Phase I proposal and the ground work laid in Phase I. The overarching goal is to prove a radically different approach to sensor packaging which offers a quantum leap in performance, cost reduction and manufacturability improvement. Preliminary testing results from Phase I indicate that the alternative technical approach to telemetry ...

Complex systems such as the AN/SPS-74(V) Periscope Detection Radar automatic target recognition system presents difficult training challenges for enhancing and maintaining operator proficiency. Technical challenges arise from the nature of software automation. The most difficult recognition cases can usually be trained effectively only with actual sensor data. Keeping the proficiency training curr ...

The Navy reduced manning requirements drive the need for more sonar automation. Automatically detecting and classifying targets of interest meets the challenge of reduced manning and workloads required for passive anti-submarine warfare (ASW) and torpedo detection, classification and localization (TDCL). The signal processing technology is comprised of a system architecture and a suite of algorith ...

Program Executive Office Submarines (PEO SUB) requires initiatives that help it achieve its Virginia Class platform cost reduction objectives as well as contributing innovative technologies to the Submarine Based Strategic Deterrent (SBSD) development and legacy classes (SSGN). To this end, PEO SUB requires technology initiatives that contribute to the goal of controlling multiple sensors using a ...

Over the last decade developments in ASW sensor systems has greatly increased the number and quality of the sensor systems deployed thus increasing the volume of data to be assessed by orders of magnitude. Data fusion concepts have been employed to help reduce the operator workload and provide decision support tools. These data fusion capabilities have focused on organic sensor track and feature d ...

The technology developed under this Phase II SBIR provides an automated collaborative data exchange capability to realize significant reduction in the time it takes for an operator to promote a contact, which requires high confidence contact validation. In particular, this technology will focus on automating data exchange between platforms in order to more rapidly: (1) produce a cross-fix solution ...

Selection of appropriate hearing protection devices (HPDs), such as earplugs and earmuffs, is important in mitigating noise-induced hearing loss among military personnel. The standard method of measuring the noise attenuation performances of HPDs is based on a psychoacoustic method involving human subjects, which is time-consuming, costly and inherently variable. It also cannot be used to measure ...

The goal of this research is to develop a comprehensive biomechanical simulation model of a full human head which includes internal anatomical features down to the minute structure of a human cochlea for accurate representation of full sound pathways to the human cochlea, including bone conduction. Such a model will provide simulation of noise energy that gets transmitted to the basilar membrane i ...

Custom fitting hearing protection earplugs have been shown to provide substantial benefits for personnel working in high noise environments such as around military aircraft and in a range of other war fighter and civilian industrial scenarios. Current manufacturing processes for shaping custom earplugs require that physical impressions be taken of customer''s ear canals. Since this involves inject ...
