Approximate calculation methods for pulse radiation of a TEM-Horn array

Simple approximate calculation methods of pulse radiation by a TEM-horn arr ay are suggested. The first one is based on substitution of the radiation f ield of each horn to a system of T V-antennas; the currents in all of these are equivalent to a single horn current distribution. The second one is ba sed on Huygens-Kirchhoff method applied for time domain. The experimental i nvestigation of radiation field by the array and comparison with results ca lculated have been carried out.
