“…Radio detection of cosmic ray air showers can provide such properties. It is for this reason that we see a revive in radio detection technique in recent years [5], [6], [7], [8]. This new approach has already been used to determine some of the key characteristics of an air shower including the arrival direction based on time measurements [9].…”

The propagation direction is one of the key parameters of an air shower. In this study we introduce a new and unique approach to determine propagation direction of an air shower based on filtered peak radio amplitudes which can shape radio signal patterns. For this purpose, a series of simulations were performed with CORSIKA and CoREAS software. Simulated air showers initiate from Proton and Iron primary particles with 10 17 eV energy and have different zenith angles from vertical to 60°. Time based results were converted and analyzed using a specially designed computer code to calculate the peak radio amplitudes of different electric field components (, ,) in the 32-64 MHz frequency band. We investigate four different shower propagation directions including North-South and East-West orientations in this paper. It is found that the radio signal patterns of different electric fields components especially the North and Vertical Components can be used to determine an air shower propagation direction accurately. This new technique is especially useful for inclined air showers where the impact of an air shower propagation direction is very prominent on its radio signal patterns.

“…In recent years there has been a significant progress in radio detection of cosmic ray air showers [2], [3], [4], [5]. New experiments [6], [7], [8] with more advanced computer simulation software [9], [10] and the agreements between the two [11] has created a hope to establish a new approach with mentioned features.…”

“…These are an artifact of the total homogeneity of the particle distributions in the simulated showers. To make statements about the emission levels in the incoherent regime (which could well be of measurable strength), one therefore needs a better air shower model, as is currently being implemented in the Monte Carlo code [6] using particle distributions derived from CORSIKA [7] simulations.…”

Cosmic ray air showers are known to emit pulsed radio emission at frequencies around a few tens of MHz. Accompanying the experimental efforts of the LOPES project, situated at the KASCADE-Grande site of the Forschungszentrum Karlsruhe, we have modeled the underlying emission mechanism in the scheme of coherent geosynchrotron radiation from electron-positron pairs deflected in the earth's magnetic field. As a follow-up to our earlier analytical calculations, we have developed a Monte Carlo simulation based on analytic parametrisations of air shower properties, including longitudinal and lateral particle distributions, particle energy and track-length distributions, and the longitudinal shower development as a whole. Here we present detailed simulation results. Important findings are the absence of significant asymmetries in the total field strength emission pattern in spite of the asymmetry introduced by the geomagnetic field, the polarisation characteristics of the geosynchrotron emission, allowing an unambiguous test of the geomagnetic emission mechanism, and the dependence of the radio emission on important shower parameters such as the shower zenith angle, the primary particle energy and the depth of the shower maximum. As a particularly useful result, these dependences have been summarized in a simple parametrisation formula, providing a solid basis for the interpretation of experimental data gathered with current and future experiments.
