Passive Bistatic Ground-Based Synthetic Aperture Radar: Concept, System, and Experiment Results
Remote Sensing, 2019 A passive bistatic ground-based synthetic aperture radar (PB-GB-SAR) system without a dedicated transmitter has been developed by using commercial-off-the-shelf (COTS) hardware for local-area high-resolution imaging and displacement measurement purposes.

Gaussian Process Regression for Estimating EM Ducting Within the Marine Atmospheric Boundary Layer
, 2019 We show that Gaussian process regression (GPR) can be used to infer the electromagnetic (EM) duct height within the marine atmospheric boundary layer (MABL) from sparsely sampled propagation factors within the context of bistatic radars.

Raw signal processing of stripmap bistatic synthetic aperture radar
IET Radar, Sonar & Navigation, 2009 Under the translational invariant (TI) configuration of stripmap imaging bistatic synthetic aperture radar (BISAR), the frequency domain expression of signal model is developed. Two forms, with an approximation of extracting the range dependence and an accurate iterative solution, as well as their respective focusing methods, that is the approximated ...
