Abstract :
Field retrieval is analyzed in this paper for the case of an antenna measurement distorted by multiple scatterers. This retrieval is carried out by filtering the effect of the obstacles. Two techniques are considered: i) computing the equivalent currents on surfaces enclosing the obstacles and the antenna; ii) computing the spherical wave expansion corresponding to each object.
