A novel algorithm for deriving diagnostics from spherical surface measurement data is described. In keeping with a `black-box' testing rationale, no initial assumptions are made as to the properties of the antenna under test. Nevertheless, high-resolution reconstructions may be generated. In the case of planar array diagnosis, single element excitation faults may be quantified to an accuracy of 0.25 dB and 2°
