Automotive Elevation Mapping with Interferometric Synthetic Aperture Radar [PDF]

open access: yesarXiv
Radar is a low-cost and ubiquitous automotive sensor, but is limited by array resolution and sensitivity when performing direction of arrival analysis. Synthetic Aperture Radar (SAR) is a class of techniques to improve azimuth resolution and sensitivity for radar. Interferometric SAR (InSAR) can be used to extract elevation from the variations in phase

SARFormer -- An Acquisition Parameter Aware Vision Transformer for Synthetic Aperture Radar Data [PDF]

open access: yesarXiv
This manuscript introduces SARFormer, a modified Vision Transformer (ViT) architecture designed for processing one or multiple synthetic aperture radar (SAR) images. Given the complex image geometry of SAR data, we propose an acquisition parameter encoding module that significantly guides the learning process, especially in the case of multiple images,
