| Abstract: | Synthetic aperture radar is a modern microwave imaging radar with high resolution in all weather all day,this paper analyses models of mono-static and multi-static,radar images are obtained using FDTD simulation and back projection,and in the end this research verify high resolution in through wall imaging using this kind of radar.Various effects of presence of the wall,such as refraction,changing in speed,and attenuation,can defocus target images,displace targets from their true positions and possibly prod... |
