<FONT face=Verdana>For high squint DBS imaging on a constant acceleration movement platform

range walk correction and quadratic phase error compensation are challenging issues.According to these two issues

this paper proposes a DBS imaging algorithm

which corrects the range walk based on the Radon transform and compensates the quadratic phase error based on the Radon ambiguity transform.And the spatial adaptability of the algorithm is also analyzed.It is easy to understand

shows good performance and needs no prior knowledge of the movement parameters and the look angle of the radar platform.Simulation results demonstrate the validity of the method.
