Echo characterization for imperfect antenna measurement systems

Wireless communication systems between two antennas are generally affected by non-idealities such as multipath effects that could modify importantly the measured values. In this paper, several post-processing methods are proposed and combined to retrieve the actual radiation pattern corresponding to the antenna under test (AUT). Once the existing reflections are identified, they can be used to correct the measured values. Experimental validation is also carried out to verify the accuracy of the proposed method.
