Paper Abstract

In Spotlight-Mode Synthetic Aperture Radar: A Signal Processing Approach, the authors describe three fundamental angles of SAR imaging: grazing, tilt, and slope. This paper extends the concept of fundamental angles used in SAR ground-mapping and apply it to the problem of imaging a moving target. A method for projecting target scattering centers of a moving target in range-doppler image coordinates will be shown. This ability should naturally result in increased performance by a model-based ATR system. Concepts are demonstrated using both a simulated array of targets and XPATCH scattering centers.
