Bsar Signal Modeling and SLC Image Reconstruction

Abstract

In this paper, a Bistatic Synthetic Aperture Radar (BSAR) signal model and Single Look Complex (SLC) image obtained by multiple satellite BSAR system are considered. Geometry and kinematics of BSAR scenario, including a BSAR satellite transmitter and multiple receivers as well as a complicated surface of observation are described. BSAR signal model based on linear frequency modulated emitted waveform and BSAR scenario is derived. Standard Fourier transformation is applied to extract an SLC BSAR image of high quality on range and cross range directions. To verify the BSAR signal model and image extraction procedure a numerical experiment is carried out.
