Abstract

Study of cosmic rays properties by measuring the radio emission generated by charged particles of extensive air showers may be an alternative method to traditional methods that use large areas of the arrays. The arrays are consist hundreds and thousands of scintillation detectors for registration of charged particles, or consist detectors, recording emission generated by relativistic particles of EAS in the optical wavelength range. Such arrays are very costly because of a large amount of detectors and complex technical equipment. On the other hand, radio method is much cheaper and easier to operate with nearly 100% duty cycle. It is sufficient to have the antenna field and a simple radio receiver tuned to a given frequency. The main problem is to choose a noise free frequency range. For this purpose, in Yakutsk was installed and started radio array for EAS radio emission. The array consists crossed antennas oriented E - W and N - S. Air shower radio registration is conducted at a frequency of 32 MHz, free from industrial noise. Yakutsk Radio Array operates since 2008. Data obtained during those several seasons includes showers with energy above 10¹⁹ eV.
