This paper experimentally explores the potential of passive multistatic SAR imaging. An experimental campaign was conducted with navigation satellites (e.g. GPS) as transmitters of opportunity. During the experiment, a single receiver recorded satellite signal reflections off a target area from 4 satellites in its field of view. Based on the total recording time and the number of signals processed, a total of 46 bistatic images were obtained. Subsequently, those bistatic images were non-coherently combined into a single multistatic image. The obtained results show that the multistatic image enhances target area information space and can additionally be used to reveal object geometric features such as edges, shape, and dimensions, which are otherwise difficult to observe in passive SAR with its modest spatial resolution. In addition, information obtained from individual images was combined to understand whether or not different object types can be classified based on variations of their bistatic reflections, with promising first results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
