The paper describes several versions of the ‘half-reflector’ impulse radiating antenna, intended for operation with high voltage sources, such as to provide electric field intensities about 70 kV/m at distances r > 20 m away from the aperture. The TEM horn feed of the antenna consists of cylindrical conductors (metal pipes), which geometry ensures a better stability against electric breakdown....
Features of impulse reflectometry using sub-nanoseconds pulses are considered. Impacts of non-uniformities in the system to the measured signal parameters are analyzed. An algorithm for observed data processing that takes into account the test signal envelope and numerous reflections originating in non-uniform system is proposed.
Features of impulse reflectometry of the sub-nanosecond range are considered. The influence of parameters of a probing signal in the ultrabroadband nonuniform systems on the results of measurements is analyzed. An algorithm of processing of measurement data that allows accounting of the shape of the probing signal and numerous reflections, originating from nonuniform systems, is proposed.
