ABSTRACT: In this proposal, the MaXentric team outlines its strategy for creating a Radar-based Compressive Sensing and Target Classification system, code-named Rad-CSC. ?In this Phase I, the team will implement and optimize compressive sensing and classification algorithms for use with conventional and synthetic aperture radar data. ?Data will be chosen from publicly available datasets, such as the MSTAR X-band SAR imagery from AFRLs Sensor Data Management System (SDMS). ?These data will be analyzed and pre-processed, with ground truths generated where necessary in order to identify targets (such as vehicles) and clutter (such as foliage). ?Compressive sampling methods will be applied in Matlab to simulate the compressive sensing process, with such algorithms being refined in order to optimally emphasize the features of the targets. ?Compressive classification techniques will then be implemented to detect and identify multiple categories of targets from the reduced-dimensionality data. ?These methods will then be extended to an existing platform by Dr. Fathy, providing a design for Phase II hardware which will implement compressive sensing & classification methods on radar imaging data. ?This design will be presented in a Phase II proposal, and the results from the Phase I study will be presented in a final demonstration.; BENEFIT: MaXentric plans to extend Rad-CSC, and its derivatives, to both military and private commercial markets. Primary military applications are the focus of this greater proposal; diverse secondary applications have been identified for examination during the course of SBIR research, including DARPA ISR (Intelligence, Surveillance, and Reconnaissance) & TRACE (Target Recognition and Adaptation in Contested Environments), lightweight target detection, warfighter awareness/targeting in contested environments, and rapid reconnaissance. ??Additional applications in the non-consumer private sector include fire/rescue C3, man-portable sensors emergency personnel, and low-energy surveillance (passive & active). ?MaXentric will also seek to explore any other identified commercialization and secondary applications of the technology developed under this STTR contract.

Our objective is to develop an intelligent communications hub, or gateway device, capable of interconnecting wearable technologies with an array of wireless local and wide area communications systems like LMR, commercial & public safety 3G/LTE, WiFi, and mesh networking. To address this, MaXentric is proposing a solution capable of not only interconnecting devices to communications networks, but also to store significant amounts of data and serve as a node for distributed local cloud computing. MaXentric will be leveraging several internally developed technologies for this effort. The LMR service of the proposed solution will utilize a LMR (P25) SDR developed by MaXentric to form an integrated device, operating in both cellular broadband and LMR networks. This offers a proven and low-risk approach for the LMR network access. Moreover, the multi-network access and mesh networking capability is utilizing a network technology in a Command and Control (C2) network solution developed for the US Army. The latter is also extended to include solutions for distributed cloud computing in mesh networks. In addition, we will assess feasibility for first responders to operate the proposed solution while wearing Personal Protective Equipment (PPE) and evaluate system maintenance & training requirements. During the Phase I effort we will draw from MaXentric team members experience of previous work with public safety technologies and utilize our relationship with the public safety community in the San Diego region. Demonstration of key concept features of the proposed solution will be presented as part of the Phase I effort.

In response to the A13-004 Remote Triage of Combat Casualties solicitation, MaXentric proposes the VitalWave system. The VitalWave system uses Doppler radar and radar imaging to assess the vital signs individuals. The use of Doppler radar allows for a system that can measure vital signs with no direct contact required. This allows first responders the ability to assess the vital signs of multiple injured soldiers from a safe distance in compromised environments. Furthermore, this technique is completely standalone and does not require victims to wear remote sensors. Another advantage of the VitalWave system is the ability to measure vital signs through walls and debris. Unlike alternative systems, which require line of sight, UWB MicroDoppler radar can identify and assess victims behind walls and rubble. The VitalWave system is light weight and power efficient allowing it to operate on a single battery charge for extended periods of time. The possibility of including further vital sign detection within the VitalWave system will also be considered. These include but are not limited to movements, location, body temperature and blood volume.

There is a growing need for compact, low cost, high resolution sensor systems capable of operating when poor weather conditions impair existing optical systems. Millimeter-wave (mmW) systems offer an excellent solution to this challenge since they are less vulnerable to these impairments while still providing higher resolution and smaller form factors than lower frequency systems. As silicon-based mmW processes continue to mature, active mmW beamforming sensors are becoming an increasingly attractive option for meeting the current situational awareness shortfall. In response to this need, MaXentric has teamed with NCSU to propose a development effort codenamed MIRAS (mm-Wave Imaging with Repurposed Arrays) focused on the design of a silicon-based W-band imaging system. As part of this effort, our team proposes to investigate the mmW imaging parameter and topology tradespace to create a prototype blueprint for future Phase II fabrication and testing. As part of the effort, our team will leverage technologies developed under several previous and ongoing mmW, beamforming, and IC prototype efforts by both MaXentric and NCSU to accelerate development and provide proof-of-concept demonstrations in Phase I.
