Monostatic and Bistatic Experiment with Airborne UHF Ultra-wideband SAR System

Ultrahigh frequency ultrawideband (UHF UWB) synthetic aperture radar (SAR) system can penetrate the foliage, get the high-resolution image, and add the scattered information, which can be used to detect the concealed area under the foliage. In fall, the monostatic and bistatic campaign with the airborne UHF UWB SAR system has been conducted. This experiment operates the airborne SAR system, in conjunction with a ground-based stationary receiver, which can simultaneously collect the monostatic and bistatic scattered data. The fast factorized back projection (FFBP) algorithm has been applied to process the monostatic and bistatic SAR scattered data, as well as the subaperture spectrum-equilibrium method. Focused monostatic and bistatic SAR images prove the feasibility and property of the developed airborne monostatic and bistatic UHF UWB SAR.
