Features of Multi-Aspect SAR Imaging Observed in an Experimental Evaluation

Multi-dimensional synthetic aperture radar (SAR) imaging includes different approaches to get more information about a target, because the reflectivity of objects in a SAR image strongly depends e.g. on the radar frequency, polarization, and viewing angle. In this paper we focus on the analysis of multi-aspect SAR, where a scene is imaged from multiple aspect angles. Objects appear very different in SAR images with a data collection from different directions. The benefits but also the challenges of multi-aspect SAR are addressed using two different objects, a church and a basalt quarry, as an example.
