“…As it can be seen in Fig.1 beside the fact that we always get the strongest radio pulses in the East-West direction due to the East-West effect from earth magnetic field [20] for a shower with this specific property, the decline in the values is very sensible. As we move away from shower cores the maximum measured value drops from 2000 to 800 ⁄ which shows a significant 60% decrease for the total field strength.…”

Future experiments based on the observation of Earth's atmosphere from sub-orbital and orbital altitudes plan to include optical Cherenkov cameras to observe extensive air showers produced by high-energy cosmic radiation via its interaction with both the Earth and its atmosphere. As discussed elsewhere [1, 2], particularly relevant is the case of upward-moving showers initiated by astrophysical neutrinos skimming and interacting in the Earth. The Cherenkov cameras, by looking above Earth's limb, can also detect cosmic rays with energies starting from less than a PeV up to the highest energies (tens of EeV). Using a customized computation scheme to determine the expected optical Cherenkov signal from these high-energy cosmic rays, we estimate the sensitivity and event rate for balloon-borne and satellite-based instruments, focusing our analysis on the Extreme Universe Space Observatory aboard a Super Pressure Balloon 2 (EUSO-SPB2) and the Probe of Extreme Multi-Messenger Astrophysics (POEMMA) experiments. We find the expected event rates to be larger than hundreds of events per hour of experimental live time, enabling a promising overall test of the Cherenkov detection technique from sub-orbital and orbital altitudes as well as a guaranteed signal that can be used for understanding the response of the instrument.

“…We start our study by analyzing the radio signal patterns for a vertical shower. The West component under the effect of the earth magnetic field and East-West effect [20] always have an orientation to the East for a shower with this specific property. In other hand the North and Vertical components have valuable information about the arrival direction of a vertical air shower.…”

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.
