A Novel Preprocessing Method for Vehicular- Mounted Forward-Looking UWB SAR System
The forward-looking ground penetrating radar (FLGPR)has been widely considered as an applicable landmines detection technology,but the self-signature and the strong ground clutter will severely degrade the SAR image.We present a novel method for interference and ground clutter suppression in the image domain based on the distance-band partition and iterative operation techniques,which can realize the parallel processing and adaptive update of the parameters on line.By using the prop- erty of FLGPR systems that the same spatial region is observed several times at different standoff distances,we exploit a range multi-look processing based on the iterative technique to obtain the high quality image.The proposed method in this paper is adaptive and efficient enough to work in a real-time operational scenario,so it can effectively meet the needs of the preprocessing in the vehicular-mounted forward-looking (VMFL)detection sys- tem.The effectiveness of our approaches is demonstrated with an experimental data set.
