Abstract :
Antenna measurement in a semi-anechoic chamber is always affected by multipath effects. In this paper, Cauchy and Gauss models of the measurement in the time domain and the noise, and the Bayesian estimation theory are applied to identify clearly the direct and reflected waves. Then, it is possible to recover the distortionless radiation pattern removing the reflected waves. Satisfactory results have been found in the comparison between retrieved radiation patterns and the reference ones.
