Phased-array effect in antennas with transient excitation

In this work the phased array effect in linear antennas with transient excitation is under theoretical and numerical analysis. This effect is realized inherently due to the specific features of transient electromagnetic radiation in long linear and other antennas. The waveform of the radiated electromagnetic field of these antennas includes, separated in time, the pulse signal replicas that are produced by specific points on antenna like its boundaries as well as any point with “strong” charge disturbance of the antenna. This waveform registered by a field probe in an arbitrary observation point depends on its spatial position. The last can be principally determined by processing of the registered waveform. This signal processing involves resolution in time of the indicated signal components and is in fact a beamforming procedure of the phased array antenna with transient behavior
