Title

Effects of translational position error on microwave synthetic aperture radar (SAR) imaging systems

Abstract

Translational position error in imaging systems can cause significant imaging quality degradation or image distortion. In this study, effects of translational position error in microwave SAR imaging system is investigated and evaluated by defining three image quality metrics. Extensive simulations are performed, in X-Band (8.2-12.4 GHz), to show the relationship between image quality and translational position error. Simulation results show that the imaging quality degrades with increasing position errors, and the sensitivity to translational position error increases as the standoff distance decreases. Measurements are also performed in X-Band for a 1D SAR imaging system. The measured results show good agreement with the simulated results. The methodology proposed in this study could be used to evaluate the feasibility or help define the required specifications of a microwave SAR imaging system for a specific application.
