Abstract

Combined synthetic aperture radar (SAR) and ground moving target indication (GMTI) radar modes simultaneously generate SAR and GMTI products from the same radar data. Furthermore, the SAR and GMTI data products can be further exploited for target signature extractions, automatic target recognition (ATR), and feature-aided tracking. This hybrid mode provides the benefit of fused imaging and moving target displays along with enhanced target recognition and ground target tracking. The Air Force Research Laboratory (AFRL) Gotcha radar has collected wide-bandwidth, multi-channel data that can be utilized for these hybrid mode applications. This paper presents a processing architecture for simultaneous SAR, GMTI, ATR, and tracking, and includes the results of applying this processing to the AFRL Gotcha data.
