Dependence analysis of emitted impulse field from the distance

Now interest to use in radiolocation of supershort video pulse signals increased. It leads to the considerable changes in the RLS equipment. Especially the theory and construction of antennas changes.The article deals with the calculation of the antennas radiation field emitting impulse fields. In the beginning the analysis of the mathematical and physical principles which describe radiation fields of antennas at different distances in case of sine signals is carried out. Results for impulse fields are given.New feature in a radiation field of pulse signals is marked: dependence of a pulse shape on the radiation direction.The new valuation principle of distance to a distant zone of radiation of different radiators in the form of a zone of formation of pulse of a field is offered.
