Using Truncated Data Sets in Spherical-Scanning Antenna Measurements

Using Truncated Data Sets in Spherical-Scanning Antenna Measurements

We discuss the mitigation of truncation errors in spherical-scanning measurements by use of a constrained least-squares estimation method. The main emphasis is the spherical harmonic representation of probe transmitting and receiving functions; however, our method is applicable to near-field measure...
