freehand

The dataset corresponding to the measurements performed in the article "Freehand System for Probe-Fed Antenna Diagnostics by Means of Amplitude-Only Acquisitions" is provided. In this work, a freehand acquisition system is used to characterize an integrated antenna fed by a GSG probe by means of amplitude-only measurements, with phase retrieval based on an indirect holography technique for broadband antennas. Spatial filtering and time-gating techniques are applied to eliminate the effect of the feeding probe.

Some novel methods for imaging based on synthetic aperture radar can result in images contaminated by artifacts as a consequence of pushing the limits of the algorithms. In order to mitigate the impact of this artifacts, image translation techniques can be exploited enabling to turn the SAR image into a cleaner one. For this purpose, multiple techniques can be used such as convolutional neural networks or generative adversial networks. However, the training of those systems can require a high number of images, which can be computationally expensive to generate.
