A Basic Fourier Transform Pair for Slant Range-Doppler Modeling of Moving Scatterers for SAR Applications: Theory

Abstract

Considering the exploitation needs associated with the Synthetic Aperture Radar (SAR) applications involving moving and non-stationary targets, a fundamental spectral domain model for moving point and distribution of scatterers is presented. The approach is accurate as the spherical phase front is rigorously treated throughout the Doppler analysis. Due to the analytic nature of the model in range-Doppler plain, large squint-angle operations (e.g., SpotSAR) can be characterized. Furthermore, motion characteristics can be extracted in the sub-aperture level to better reflect the general motion (e.g., non-uniform). As a result, enhanced adaptivity can be achieved to improve the imagery and other target-signature measured products. The range- Doppler model can serve as a tool for polarimetric and multi-channel analysis.
