A Real-Time Implementation of a DPCA GMTI Technique for a UAV SAR Demonstrator System Developed by the CSIR

This paper presents a real-time Displaced Phase Center Antenna (DPCA) Ground Moving Target Indication (GMTI) processor. The GMTI processor performs clutter suppression, target detection, target tracking and target geolocation in real-time on a C-band airborne UAV radar demonstrator system. The processor is implemented on the GPU to meet the real-time performance requirements. A clutter suppression extent of 12.1 dB is achieved per frame in real-time.
