Abstract [en]

Left/right ambiguity and low Doppler resolution are severe problems for monostatic forward-looking SAR imaging. Among approaches for the problems, using bistatic SAR is very promising. The left/right ambiguity in bistatic forward-looking SAR has been investigated in detail recently whereas an appropriate study for enhancing bistatic forward-looking SAR Doppler resolution is still desired. A research on Doppler resolution and then cross-range resolution in bistatic forward-looking SAR is therefore presented in this paper. The research is based on the use of the gradient. Several recommendations which allow maximizing Doppler resolution and cross-range in bistatic forward-looking SAR imaging are provided. © 2015 IEEE.
