Remote sounding of fields in feed radiators of multi-element antenna system with allowance for interaction with sounding device
Abstract
An antenna system incorporating an arbitrary type of distribution system and a multielement antenna array is sounded in order to recover the complex amplitudes of the incident waves on the inputs of the array feeds from the responses (readings) of the amplitude and phase meter of the sounding device measured in the near field of the array. The distribution of the complex amplitudes is recovered by means of a linear operator which takes into account the electrodynamic interaction of the probe and the antenna system. Amplitude phase distribution recovery error caused by failure to account for interaction between the sounding system and the antenna system is modeled by computer. Analogous methods can be employed in order to investigate interaction effects in an antenna array probe device system and to recover the amplitude phase distribution of the currents and voltages at the inputs of the radiators.
