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…
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…
