ABSTRACT: A new approach to multisensor fusion is proposed that utilizes a knowledge-aided (KA) multi-physics model as the main fusion engine, as opposed to traditional purely statistical methods. The new Multi-Physics Sensor Fusion (MPSF) is enabled byadvances in high performance computing, knowledge-aided (KA) processing, and new techniques in multi-physics modeling. Traditional sensor fusion ou ...

ABSTRACT: Laser source technology in the mid-infrared region, 2um to beyond 10um, is progressing rapidly. Quantum cascade laser (QCL) is one of these new sources, which cover the whole mid-infrared spectrum with high-power and good wall-plug efficiencies. Due to the micron sized and non-circular cross-section of the active region, the laser beam quickly diverges in the direction perpendicular to t ...

ABSTRACT: In this Phase I effort, the PI2 team will perform a set of technology and algorithmic trade studies with the goal of finding innovative new system concepts for a VPHS using all digital processing, and with extremely low latency (at most one frame) from light into the sensor to light out of the display. We approach this attempting to meet the system threshold and objective goals as stated ...

ABSTRACT: The rapid continued development of unmanned air systems (UAS) is enabling new mission types, in-creased mission effects, and increased airman safety. However, these advances also present numerous challenges to airman-machine interaction, tactics development, and defense. The rapid development pace has produced a situation where new technologies are outpacing the knowledge of how best to ...

ABSTRACT: This project addresses the development and evaluation of high-quality low-dimensional (HQLD) sensor data selection and fusion (SDSF) algorithms. The objective is to develop algorithms that process the data from multiple sensors to reduce dimensionality while retaining the information content of the full-dimension data. An HQLD-SDSF algorithm will be developed within the context of a like ...

ABSTRACT: Information geometry treats families of probability distributions as curves or surfaces in an abstract space of probability distributions. Theoretical results from this field exist in multiple application domains and at least some real systems employ data fusion techniques based on this research. We propose the combination of techniques that have been developed and applied for different ...

ABSTRACT: Vocal communication in the real world often takes place in complex and noisy acoustic environments. For applications such as mobile communications or use of automated speech/speaker recognition algorithms on recorded data, the presence of noise and reverberation significantly degrades the quality and intelligibility of speech and severely hampers the performance of these systems. Approac ...

ABSTRACT: Despite decades of research, machine hearing continues to be far less robust than human hearing. The difference is especially noticeable in reverberant environments which pose a critical limitation on the general utility of Human Language Technology. Voci Technologies Incorporated (Voci) is the leading small business developing accelerated Human Language Technology based solutions. Voci ...

ABSTRACT: Mayflower proposes a novel Positioning, Navigation and Timing (PNT) solution specifically designed for use in challenging RF environments (intentional or unintentional jamming and spoofing) that enables uninterrupted navigation capability for wide ranges of military and commercial applications. Tactical units with spectrum sensing capable cognitive radios (CR) or scanners deployed in the ...

ABSTRACT: Echo Ridge (ER) proposes to design an architecture and key algorithms to support spectrum sharing for PNT that focuses on spectrally congested and high likelihood operational scenarios. The architecture defines the new functionality/necessary improvements to the PNT elements (broadcasts satellite and MGUE DSA operation), spectrum sensing elements (signal sensing detection/characterizatio ...
