Abstract
A coherent radio emission from particle shower in a dielectric medium, so-called Askaryan pulse, has been recorded in a laboratory setting. In this report the analysis of measurement made with a broadband (1-18 GHz) log periodic dipole antenna (LPDA) is described. The properties of the observed radio pulses are compared with the current theoretical model. The radiation intensity as a function of frequency was found to agree well with the expectation, while the phase characteristics of pulses disagree with the theoretical work.
