Preliminary Goniopolarimetric Simulations for Space Weather Radio (SWARA) Polarimeter
Abstract
Goniopolarimetry is a technique that measures the direction-of-arrival (DoA) using the polarization properties of the incident electromagnetic (EM) waves. This study aims to incorporate the technique of Goniopolarimetry for our proposed polarimeter, Space Weather Radio (SWARA) Polarimeter, to provide early warnings for space weather or solar events. We have performed preliminary simulations for a tri-monopole antenna configuration. The behaviour of the tri-monopole antenna with varying signal-to-noise (SNR) ratios along the field-of-view (FOV) was investigated using simulations. The angular localization error (ALE) variations, along with SNRs, were simulated to quantify the sensitivity of the Goniopolarimetric algorithm to galactic background noise. Future work will focus on determining the optimum effective length of the individual monopoles to maximize sensitivity and localization accuracy while ensuring efficient impedance matching with the receiver. The optimized antenna will be evaluated under realistic plasma environments through electromagnetic and plasma simulations to investigate the influence of plasma parameters.
