| Abstract: | In this work,an approach based on the ray technique for the simulation of the SAR image of the building is proposed.In this approach,the ray technique and the physical optics are employed to calculate the multi-path scattering of the building,also the SAR image formation is used to get the SAR image of the building. Furthermore,simulations are implemented on the building with flat roof and slope roof.The results tests the validity of the approach proposed.And it is hope that the approach in this work could be some help for the feature extraction and reconstruction of the building from the SAR image. |
