A combination of techniques is described for reliably estimating the magnitude of each error arising in planar near-field measurements. They include mathematical analysis, computer simulation, and measurement tests. There are three primary applications for these tests: in designing a measurement facility, the requirements of each part of the measurement system can be specified to meet a given level of accuracy; during actual measurements, the experimenter can identify, and reduce where necessary, potential sources of error in the measurement; and when a measurement has been completed, the estimated uncertainty in the measurement can be obtained with confidence and ease. The latter application has been used in many measurements to verify that the planar near-field technique produces high-accuracy results competitive with any other measurement technique. >read more

Accurate diagnosis of conformal arrays from near-field data using the matrix method
TL;DR: In this article, a matrix method for array diagnosis is proposed based on the reconstruction of the excitation from measured near-field data by solving the linear system relating the excitations coefficients to the field at the measurement points, which is applied to the diagnosis of element failures in high-performance conformal array radar.
