Moving Target Detection and Motion Estimation in Foliage using Along Track Monopulse Synthetic Aperture Radar Imaging.

Abstract : A system model for the effect of uncalibrated monostatic and bistatic radars via gain and phase functions which vary with the radars aspect angles and the radar frequency, and the resultant degradation in monopulse SAR images and their difference which is used for moving target detection, is developed. A signal subspace processing of monopulse SAR images and a signal subspace difference image for moving target detection, which is not sensitive to the unknown gain and phase error functions of the uncalibrated radars, are developed. Numerical results are provided.
