Abstract
We have studied the radiative characteristics of the explosive action in the atmosphere. It has been shown that even a single explosive action produced simultaneously with a high-frequency (HF) discharge forms an effective plasma antenna. In the absence of an HF discharge, an explosive action with a specific arrangement of point explosions allows the generation of a convergent shockwave of pressure and magnetic field. As a result, a waveguiding disturbance of the background plasma is formed in the convergence region of the shockwave; given the simultaneous excitation of pulsed fields in the near-frontal region, this also leads to the formation of a plasma antenna at high altitudes.
