In this thesis we study the Cherenkov radiation pulse from ultra-high energy particle shower by a numerical finite-difference time-domain (FDTD) method. Expounding the work on ANITA experiment include detection method, instrument and operation method. The design concept of Askaryan Radio Array (ARA) experiment and the hardware, deploy and operation. We propose our strategy to identify the neutrino flavor in observing cosmogenic neutrinos by radio neutrino telescopes, such as ARA, ARIANNA.
