Abstract :
The aim of this work is to get far field radiation patterns for any radiating source from transient acquisition, in a large frequency range. An outdoor transient Ultra-Wideband near-field measurement base has been installed, a single time pulse radiated by the source covers the desired spectrum, and the accurate determination of far field radiations is accomplished by means of cylindrical waves´ modal development. This method uses simplified test equipments, easy to be installed, and it reduces measurement costs.
