Abstract :
In this paper an iterative technique for antenna diagnosis and pattern reconstruction from amplitude field data at two distances is presented. At each iteration, phase correction is accomplished using a source reconstruction optimization method. Results from synthesized data, even in the case of typical measurement errors, illustrate the validity of the technique.
