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.

ABSTRACT: The vulnerability of satellite assets to enemy jamming has led to an increased urgency to develop SATCOM payloads capable of maintaining high aggregate throughput even in challenged environments. As the size, cost, and power consumption of digital signal processing platforms continue to drop and their performance improves, incorporating digital beamformer (DBF) designs into future SATCOM satellite payloads has become an increasingly attractive solution to this challenge. The flexibility of digital beamforming permits the creation of multiple independent antenna patterns that can be designed for wideband systems. In response to the Air Force solicitation, MaXentric is developing an adaptive digital beamforming system codenamed SABER (Satellite Adaptive Beamforming aRray). MaXentrics Phase I focused on simulating critical adaptive beamforming algorithms while reviewing the system trade space. The proposed Phase II effort will focus on constructing a hardware test platform for algorithm implementation and testing. BENEFIT: SABER Phase 2 HW prototype provides a fully functional HW implementation of the SABER architecture envisioned in Phase 1. It will enable MaXentric to implement the various flexible, power efficient algorithms for beam-forming and channel equalization developed and analyzed in Phase 1. MaXentric Phase 2 approach emphasizes the need for commercializing the SABER platform by building a Phase II prototype that has enough flexibility and functionality to be utilized in many other government and private sector applications such as phased array radars and sensing, MIMO transceivers targeted for SIGINT or wireless/cellular communications and general purpose DSP boards used for complex and demanding wide-band signal processing tasks.

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.

ABSTRACT: To meet the demands of the A141-245 SBIR solicitation, the MaXentric ) team proposes the GAM (Green Amp Multiplexer), which uses compact microwave circuit design and digital distortion compensation algorithm to expand bandwidths and reduce insertion losses of a multipaction-free multiplexer system for the global positioning system (GPS) block-III satellite. As a result of Phase I efforts, MaXentric proposed a concept of a compact multiplexer system consisting of planar multiplexer and multiple-band power amplifiers (PAs), which are integrated into one module. An additional concept was proposed to compensate for the imperfection of the multiplexer system, such as filter roll-off and PA non-linearity, through the use of digital signal processing (DSP) techniques. These innovative concepts enable the GPS multiplexer system to extend the bandwidths (up to 45 MHz) without sacrificing insertion losses (
