Reliable Linearized Phase Retrieval for Near-Field Antenna Measurements with Truncated Measurement Surfaces
Alexander Paulus, Josef Knapp, Jonas Kornprobst +1
Most methods tackling the phase retrieval problem of magnitude-only antenna measurements suffer from unrealistic sampling requirements, from unfeasible computational complexities,…
Multi-Frequency Phase Retrieval for Antenna Measurements
Josef Knapp, Alexander Paulus, Jonas Kornprobst +2
Phase retrieval problems in antenna measurements arise when a reference phase cannot be provided to all measurement locations. Phase retrieval algorithms require sufficiently many…
Linear Phase Retrieval for Near-Field Measurements with Locally Known Phase Relations
Alexander Paulus, Jonas Kornprobst, Josef Knapp +1
A linear and thus convex phase retrieval algorithm for the application in phaseless near-field far-field transformations is presented. The formulation exploits locally known phase…
Improved Discretization of the Full First-Order Magnetic Field Integral Equation
Jonas Kornprobst, Alexander Paulus, Thomas F. Eibert
The inaccuracy of the classical magnetic field integral equation (MFIE) is a long-studied problem. We investigate one of the potential approaches to solve the accuracy problem: hig…
Accuracy and Conditioning of Surface-Source Based Near-Field to Far-Field Transformations
Jonas Kornprobst, Josef Knapp, Raimund A. M. Mauermayer +3
The conditioning and accuracy of various inverse surface-source formulations are investigated. First, the normal systems of equations are discussed. Second, different implementatio…
Phase Retrieval for Partially Coherent Observations
Jonas Kornprobst, Alexander Paulus, Josef Knapp +1
Phase retrieval is in general a non-convex and non-linear task and the corresponding algorithms struggle with the issue of local minima. We consider the case where the measurement…
