Incoherent microwave radiation of an extensive air shower

Incoherent radiation of relativistic electrons (positrons) of an extensive air shower in the ultrahigh energy range ($\sim10$ GHz) has been studied. The method of the division of an electron track into coherent segments has been used to estimate the power of a radio signal and to determine the radiation pattern. Comparison of the signal with radio noise of an antenna has shown that this radiation can be detected by modern engineering instruments and applied to detect ultrahigh-energy cosmic particles.
