Afixed-receiver mobile-transmitter passive bistatic syntheticaperture radar (MF-PB-SAR) system, which uses the Sentinel-1 SARsatellite as its non-cooperative emitting source, has beendeveloped by using embedded software-defined radio (SDR) hardwarefor high-resolution imaging of the targets in a local area in thisstudy. Firstly, Sentinel-1 and the designed system are introduced.Then, signal model, signal pre-processing methods, and effectivetarget imaging methods are presented. At last, various experimentresults of target imaging obtained at different locations are shownto validate the developed system and the proposed methods. It wasfound that targets in a range of several kilometers can be wellimaged. https://www.mdpi.com/2072-4…
