Arc Array Bistatic Synthetic Aperture Radar for Full Azimuth Imaging

Abstract

The arc array bistatic synthetic aperture radar (SAR) full azimuth imaging based on arc antenna array is studied. Compare with the conventional arc array monostatic SAR, advantages of the arc array bistatic SAR are that it can avoiding physical attack of the imaging platform and obtain additional information contained in the bistatic reflectivity of targets. In this paper, the imaging geometry of the arc array bistatic SAR is presented and the signal model based on this imaging geometry is established. The resolution of arc array bistatic SAR is analyzed. In addition, the arc array bistatic SAR imaging algorithm is given and validated by simulation results.
