Abstract
Images of suitable quality can be used for detection, classification, identification, and precision targeting. Synthetic aperture radar (SAR) systems are capable of providing such images from standoff ranges. These systems, however, typically image stationary targets and have limited or no capability to image moving targets. Moving target imaging (MTIm) provides a means to focus movers in SAR imagery. Proof of concept was demonstrated by Grumman as early as 1991 using a long range, high resolution radar platform to image moving targets. The radar platform is a key factor in any imaging experiment. Various radar parameters such as range, PRF, resolution, and phase center separation must be analyzed to fully appreciate the advantages as well as the potential caveats associated with a given platform. The results of theoretical analysis and numerical simulations used to evaluate the effect of system parameters on imaging are described and studies regarding the challenges specific to long range MTIm are presented.
