Spherical Scanning Measurements Using Truncated Data Sets



Ronald C. Wittmann, Carl F. Stubenrauch, Michael H. Francis


We discuss the mitigation of truncation errors in spherical scanning measurement. The main emphasis is the spherical harmonic representation of probe transmitting and receiving functions; however, our method is applicable to near-field measurement of electrically small antennas for which full-sphere data are either unreliable or unavailable.
