| Abstract(in English) | In recent years, bistatic synthetic aperture radar technique has attracted considerable and increasing attention. Compared to monostatic SAR for which only backscattering is measured, bistatic SAR expands the scattering measurements in aspects of angular region and polarization, and greatly enhances the target detection and classification. It has been pointed out in recent studies that bistatic scattering measured in the forward region is preferable than that measured in the backward region, in lines of surface parameters retrieval. In the forward region, both dynamic range and signal sensitivity increase to a great extent. For these reasons, SAR imaging in both backward and forward is desirable. However, because the separated positions of the transmitter and receiver level up the degree of freedom in the parameters space, the bistatic SAR imaging is more complicated than the monostatic SAR imaging, in terms of bistatic range history, two-dimensional resolution, Doppler parameter estimation, and motion compensation, and so on. In this study, we analyze bistatic SAR range history and ground two-dimensional resolution with a large baseline between transmitter and receiver and a large bistatic angle in the forward imaging zone. The result helps to deepen understanding of the constraints and performance of bistatic SAR imaging. |
