Measuring and deconvolving frequency response of SURA-4 as a cosmic-ray radio-array experiment
Abstract
Semnan University Radio Array is a radio experiment aiming to detect ultra-high-energy cosmic rays and investigate their properties using radio-signal analyses. The first phase of this experiment is operational on the roof of the physics faculty of Semnan University. Investigating important cosmic-ray properties, including the primary particle's energy scale, requires comparing experimental data and simulation-based studies. This necessitates measuring and deconvolving the frequency response of the experiment. In this study, we measure the frequency response of the SURA-4 electronic chain and perform a computer simulation of the Log-Periodic Dipole Antenna to obtain the system frequency response of the SURA-4 setup. We describe the procedure of deconvolving the measurements on the experimental data to reconstruct the strength of the electric field trace. The result makes it possible to investigate important cosmic-ray properties by comparing experimental data with simulation-based studies.
