Abstract
Results obtained from the measuring the radio emissions from extensive air shower particles with energies higher than 5 × 1018 eV at a frequency of 32 MHz are presented. A generalized formula is derived to describe the spatial distribution of radio emissions using the main EAS characteristics: energy Е 0 and depth of maximum development of shower Х max. The approximating function describes the data at average and large distances from a shower axis. The ratio of signal amplitudes at distances of 175 m and 725 m is used to determine Х max for an average shower with an energy of 1.54 × 1019 eV, which in our case is equal to Х max = 769 ± 34 g cm−2. Within the experimental error, the result for Х max is consistent with data obtained using EAS Cherenkov light.
