Bergin and Paul M. Techau Information Systems Laboratories Inc. 8130 Boone Boulevard Suite 500 Vienna VA 22182 USA Received 1 November 2004 Revised 15 April 2005 Accepted 25 April 2005 Synthetic aperture radar SAR exploits very high spatial resolution via temporal integration and ownship motion to reduce the background clutter power in a given resolution cell to allow detection of nonmoving targets. Ground moving target indicator GMTI radar on the other hand employs much lower-resolution processing but exploits relative differences in the space-time response between moving targets and clutter for detection. Therefore SAR and GMTI represent two different temporal processing resolution scales which have typically been optimized and demonstrated independently to work well for detecting either stationary in the case of SAR or exo-clutter in the case of GMTI targets. Based on this multiresolution interpretation of airborne radar data processing there appears to be an opportunity to develop detection techniques that attempt to optimize the signal processing resolution scale e.g. length of temporal integration to match the dynamics of a target of interest. This paper investigates signal processing techniques that exploit long CPIs to improve the detection performance of very slow-moving targets. Copyright 2006 J. S. Bergin and P. M. Techau.
