“…In order to test the proposed procedures in hard phaseretrieval scenarios, all numerical examples (except for the last one) have been performed by adopting, as in [27], random array excitations. Moreover, a test case dealing with the PR of a 'structured' electromagnetic field of interest in the applications and having a very large excitations dynamics is also given.…”

“…In order to make the whole periodicity range of the power spectrum available for measurements (see [27] for more details), an inter-element spacing of = =0.707 has been adopted for all the following examples.…”

“…Notably, additional difficulties may arise in the particular problem one is dealing with. In antenna testing, for example, even assuming the antenna is a uniformly spaced array (so that the spectrum is periodic), depending on the element spacing one may not be able to collect the whole square amplitude distribution of the Fourier Transform of the unknown signal in the basic periodicity cell (see [27] for details).…”

We propose an innovative approach to the phase retrieval of 2-D discrete complex signals. The solution strategy profitably exploits some fundamental results available for the phase retrieval of one-dimensional discrete signals by following a simple yet effective philosophy resembling the solution of crossword puzzles. The resulting procedure is completely deterministic and allows identifying all the solutions of the problem by using just the spectral amplitude data, knowledge of the support of the source, and a few additional information. As a distinguishing characteristic, it does not exploit neither globaloptimization algorithms nor iterative techniques. Numerical examples witnessing the interest of the proposed ideas are given for antenna applications.

“…Besides, phase measurements are more sensitive to geo-referring uncertainties. An alternative to the use of complex receivers is provided by phase retrieval techniques, capable of recovering phase information from amplitude-only measurements [14,15,16,17,18,19]. Once the phase of the field is retrieved, NF-FF transformation techniques can be applied to calculate the AUT radiation pattern.…”

“…Thus, for on-site NF antenna measurements using UAVs, the latter group of methods is more suitable, allowing a faster and easier deployment of the system. Nevertheless, recent developments in phaseless antenna measurement techniques using a single acquisition surface [19] are a promising solution aiming to avoid the need of two acquisition surfaces.…”

On-site antenna measurement has been recently attracting an increasing interest in order to assess the antenna performance in real operational environments. The complexity and cost of these kind of measurements have been significantly cut down due to recent developments in unmanned aerial vehicles’ (UAVs) hardware and antenna measurement post-processing techniques. In particular, the introduction of positioning and geo-referring subsystems capable of providing centimeter-level accuracy together with the use of phase retrieval techniques and near-field to far-field transformation algorithms, have enabled near field measurements using UAVs. This contribution presents an improved UAV-based on-site antenna measurement system. On the one hand, the simultaneous acquisition on two measurement surfaces has been introduced and calibrated properly, thus reducing geo-referring uncertainties and flight time. On the other hand, the positioning and geo-referring subsystem has been enhanced by means of a dual-band real time kinematics (RTK) unit. The system capabilities were validated by measuring an offset reflector antenna, and the results were compared with the measurements at the spherical range in the anechoic chamber and with the measurements collected with a previous version of the implemented system.
