Abstract

Due to the intrinsic property, ultrahigh frequency ultrawideband (UHF UWB) synthetic aperture radar (SAR) has lately become of a particular interest to the SAR community. Monostatic and bistatic UHF UWB SAR has the well foliage penetrating ability, high-resolution imaging and providing the increased information. In 2015, the monostatic and bistatic UHF UWB SAR experiment has been conducted. In this experiment, the monostatic and bistatic data were collected simultaneously by operating the vehicle-based radar in the SAR mode, in conjunction with the stationary ground-based receiver. Bistatic and monostatic SAR images were obtained by the subaperture spectrum-equilibrium method integrated with a fast factorized back projection (FFBP) method. Experiment results prove the property of the monostatic and bistatic UHF UWB SAR.
