Fast Post-Doppler STAP with Road Map for Traffic Monitoring

Abstract

Synthetic aperture radar (SAR) is an efficient solution for road traffic monitoring due to its high spatial resolution and independence from daylight and weather conditions. Several ground moving target indication (GMTI) algorithms have been developed, whereas their robustness is often achieved with high costs, hardware complexity and computational burden. This paper presents a fast GMTI processor that blends the powerful post-Doppler space-time adaptive processing (PD STAP) with the OpenStreetMap (OSM). The algorithm has great potential for real-time processing, decreased hardware complexity and low costs compared to state-of-the-art systems. It is tested using 4-channel data acquired with DLR’s airborne F-SAR.
