Airborne Multi-channel Antenna SAR Adaptive Clutter Suppression

LI Chun sheng,CHEN Jie,ZHOU Yin qing(Dept.of Electronic Engineering,Beijing University of Aeronautics and Astronautics,Beijing 100083,China)  
On the basis of multiple channel antenna SAR geometry relation,a completed multi channel antenna synthetic aperture radar (SAR) echo signal model is built and the multi channel antenna SAR adaptive clutter suppression method and practical structure based on phased array antenna forming multiple receiving channel antenna using the spatial element repetition structure are presented in this paper.Conclusion can be drawn from theoretical analysis and computational simulation that it can achieve good low speed moving target detection performance in airborne SAR imaging by combining multiple channel antenna technology with spatial temporal adaptive clutter suppression technology.
