Use of the Synthesized Short Radio Pulse for Near-Field Antenna Measurements
This paper considers a mirror parabolic antenna near-field, which is synthesized by measurements at a discrete number of frequencies with the following Fourier transformation of data into time domain, where separation of the signal components with different propagation occurs. Identification of these components taking into account the geometry of the measurement facility and the inverse Fourier transformation of a part of them allows us to define more accurately the antenna near field, as well as to define the interference field. The efficiency of such measurements is defined first of all by the band and the discrete of the frequency variation choosen.
