Rail-UWB-SAR system has such merits as controllable
repeatable
and low-cost
and is an effective means to study UWB SAR.A new experiment method to solve LFM radar range `dead' area
bistatic SAR
was presented in the paper.The bistatic SAR imaging algorithm was studied.The feasibility of the experiment method was confirmed by experiment results.The accuracy of Rail system was analyzed.Lastly
the disadvantage and its application were discussed.
