“…The values of the peak radio amplitudes decrease rapidly as we move from the shower core to further distances. These two type of figures are almost identical four all kind of cosmic rays regardless of their initial energy and type of primary particle as we discussed in [3]. These patterns also contain some valuable information about the arrival direction of a cosmic ray [15].…”

“…Radio detection of cosmic ray air showers has experienced a great progress in the last decade. This new method is the most suitable for ultra high energy cosmic rays [3]. Since these ultra high energy cosmic rays deflect less in galactic and extragalactic magnetic fields [2], [4], it is even possible to determine some source candidates of cosmic rays beside obtaining key parameters like the type and initial energy of the primary particle by studying radio measurement only [5].…”

Different type of mechanisms are involved in creation and propagation of radio signals from cosmic ray air showers. The geomagnetic origin is one of such procedures which is very important especially in low frequency band radio studies. Based on CORSIKA and CoREAS code, we investigate the influence of the Earth magnetic field parameter on filtered peak radio amplitude patterns in 32-64 MHz frequency band using a specially developed computer code. Simulated air showers are from Proton and Iron primary particles with 10 17 eV initial energy. We investigate vertical (θ = 0 0) and inclined (θ = 60 0) cosmic rays with φ = 0 0. It is found that radio signal patterns from inclined cosmic rays are heavily dependent on the Earth magnetic field values and as a result of that some radio patterns change fundamentally as we move from a location in the Southern to a new place in the Northern hemisphere. We have chosen Pierre Auger Observatory and a location where we hope to have a new radio array in near future. Analyzing these patterns can clearly confirm the importance and influence of the Earth magnetic field parameter on the radio signal patterns from cosmic ray air showers.

High energy cosmic rays hitting the earth atmosphere induce extensive air showers propagating downward with a high gamma factor. Determining the core location of such air shower is a necessary step to measure other important characteristics of a cosmic ray such as the lateral distribution function. In this study and based on computer simulations and radio signal analyses we investigate the relation between normalized radio signal phase angle emitted from particles in an air shower to the position of a shower core. We perform a series of simulations based on CORSIKA and COREAS code for cosmic rays with different types of primary particles with an energy range from 0.1 to 1 EeV. The results show a direct relationship between the average slope of normalized radio signal phase angle as a function of frequency to the absolute distance from extensive air shower core location. We have calculated the normalized radio signal phase angle to have the absolute minimum value at close distances to a shower core location. We discuss a possible approach to estimate core location with different types of virtual radio arrays.
