Abstract: The pulsed antenna near-field measurement technique is a novel antenna measurement technique developed since the 1990's. Pulse parameters of the transmitted signal are presented in this paper. With the plane-wave theory of time-domain fields, computing formulas of the far-field pattern are obtained. A setup scheme of the pulsed antenna near-field measurement system adaptable to practical requirements is given. Finally, some questions that ought to be paid attention to in pulsed antenna near-field measurement is analyzed on the basis of measured near-field data.

Key words: pulse antenna, antenna measurement, microwave receiver
