The Representation of Moving Targets in Multi-channel UWB SAR Images and Its Application in the Generalization of Image Domain GMTI Methods

摘要：

To generalize the image domain GMTI methods for slow moving targets to be suitable for detection fast moving targets with multi-channel ultra-wide band (UWB) SAR system,the representation of moving targets in multichannel UWB SAR images is studied in this paper.By analyzing the Local Back Projection (LBP) SAR imaging process for the moving target,this paper gives the analytic expressions of the moving target in the multi-channel UWB SAR images.Following the results,the image domain GMTI methods can be generalized to be suitable for fast moving targets that defocus in multi-channel UWB SAR images.This generalization is demonstrated via the ATI method.
