GMTI is focused on detection and geolocation of vehicles and personnel moving on the ground, while SAR produces fine-resolution imagery of stationary objects. These modes, while similar on the surface, have historically been realized with very different and dedicated hardware and software. More recently, however, multi-function radar systems have enabled a blending of these heretofore distinct modalities. This tutorial will begin with a quick review of air-to-ground radar operation, quickly moving into a comparison and contrasting of the SAR and GMTI modes. Next, a detailed description of the implementation and processing behind these modes will be presented. Finally, several examples of combined modes, applications sharing attributes of both SAR and GMTI, will be examined. SPEAKER Dr. Gregory Showman Principal Research Engineer, GTRI Dr. Gregory Showman is a Principal Research Engineer and heads the Adaptive Sensor Technology Branch at GTRI. He has over 25 years of experience in advanced RF sensor research and development, with an emphasis on the design and implementation of innovative signal processing techniques for radar imaging, electronic protection, and multi-dimensional adaptive filtering. Dr. Showman's accomplishments include development of novel techniques for ultrawideband SAR and high-precision turntable inverse SAR image formation, methods for polarimetric SAR calibration, electronic protection against jamming, and STAP algorithms and architectures for airborne and space-based GMTI systems. His current efforts are focused on the development of robust algorithms and architectures for STAP and problems related to electronic warfare for SAR and GMTI sensors. Additionally, Dr. Showman is a Senior Member of the IEEE and author of two chapters in the Principles of Modern Radar books, both on the topic of SAR imaging. This AOC webinar is COMPLIMENTARY, unclassified, and all participants are welcome.
