| Abstract: | A fast novel method is presented,that combines SBR and EEC techniques with radar chirp signal processing.This fast method gives an order of magnitude speedup in computation time compared with conventional methods.With the wide radar signal data obtained by this method,range profiles and ISAR images are obtained,which validated the accuracy and efficiency of this fast method. |
