“…In the context of the in-situ calibration, step 1 consists in implementing (26) and (27) immediately after the initial calibration to obtain a factory standard status set of K r n | bef and K t n | bef values, while step 2 repeats the same procedure as step 1, but at the operation location, to obtain a new set of K r n | aft and K t n | aft values. Finally, to cover step 3 and calculate the amplitude and phase deviation from the factory standard use,…”

“…However, large phase errors are not expected to arise during operation, unless the active element antenna and/or electronics have been damaged, in which case, it should be neglected from the calibration. Also, expressions (26) and (27) are prone to error propagation, i.e., measurement errors, as noise or repeatability, are present on each K n,m term, and they will accumulate along the ratio path. In other words, the longer the ratio path, the greater the possibility of larger accumulated error.…”

“…An method, which is the expansion of projection matrix correction method in [3], is presented for the wideband PPAR [15]. In addition, because of the inevitable distortion of radiation pattern mainly resulting from the mutual coupling [16], the correction matrix using the theoretical pattern is not completely effective. To mitigate the effect of non-ideality on the polarization measurement, a pattern reconstruction method is put forward in [17], [18].…”
