A new SAR imaging scheme in foreign object debris detection

Abstract

Foreign object debris (FOD) poses a significant hazard to aviation safety and brings huge economic losses to the aerospace industry due to aircraft damage. Different schemes and sensors have been utilized for FOD detection. In this paper, we propose a new method of synthetic aperture radar (SAR) imaging, which can be used in airport runway foreign object debris (FOD) detection, and study its feasibility. We then use the filtered back-projection algorithm for a two-dimensional imaging simulation. The simulation results show that the method is feasible.
