TL;DR: The TARA detector combines a 40kW, 54.1MHz VHF transmitter and high-gain transmitting antenna which broadcasts the radar carrier over the surface scintillation detector (SD) and within the FD field of view, towards a 250-MS/s DAQ receiver.

TL;DR: This analysis includes the prediction of an impact offset parameter (and its uncertainty) in a representative player interaction scenario, and using realistic radar specifications from existing hardware.
Abstract: In this paper, we analyze the performance of a helmet-based Frequency Modulated Continuous Wave (FMCW) radar system used for impact prediction in contact sports, or other risky environment. Such a prediction tool could be used as part of a larger, helmet-based system for mitigating neurological damage caused by impacts. Mitigation strategies could leverage imminent impact information for use in an audible warning system or for dynamic preloading and control of an active helmet suspension. Our analysis includes the prediction of an impact offset parameter (and its uncertainty) in a representative player interaction scenario, and using realistic radar specifications from existing hardware.

TL;DR: An analytical approach to calculate the far-field radiation pattern of conformal arrays, consisting of arbitrarily oriented antennas, focuses on spherical arrays of microstrip patch antennas, and reduces the computational time and resource requirements as compared to a full-wave conventional EM solver.
Abstract: In this paper, we present an analytical approach to calculate the far-field radiation pattern of conformal arrays, consisting of arbitrarily oriented antennas. In particular, we focus on spherical arrays of microstrip patch antennas. This approach reduces the computational time and resource requirements as compared to a full-wave conventional EM solver. It should be mentioned that this method is not limited to spherical arrays only and can be applied to any other configurations as well. Also, this analytical approach makes it possible to run optimization processes faster, and to meet various design objectives.
