Simulated bi-SQUID Arrays Performing Direction Finding
Abstract
One of the High Temperature Superconductor (HTS) bi-Superconducting Quantum Interference Device (SQUID) Array Fractional Wavelength Baseline Determination and Design Study team s goal was to determine whether the raw simulated output from an array of bi-superconducting quantum interference devices (bi-SQUIDs) could perform direction-finding (DF) tasks such as the angle of arrival (AoA), elevation, and polarization. First, we applied the multiple signal classification (MUSIC) algorithm on linearly polarized signals. We included multiple signals in the output both of the same frequency and different frequencies. Next, we explored a modified MUSIC algorithm called dimensionality reduction MUSIC (DR- MUSIC), which can handle elliptical or circular polarizations. Finally, we explored the six-element Poynting vector method.
