Analysis of Matched Filter Mismatch for Focusing Moving Targets in Multi-channel Synthetic Aperture Radar

Abstract

This report derives the matched filter necessary for focusing moving targets in multi-channel Synthetic Aperture Radar (SAR) systems after clutter cancellation has been performed. The Displaced Phase Centre Antenna (DPCA) is utilized to achieve the clutter cancellation in a two channel SAR system. After deriving the matched filter, the tolerance of the filter is then analyzed for mismatches against errors in the moving targets position and velocity components. The tolerances are quantified for two exemplar SAR systems; an X-band airborne SAR and a C-band satellite SAR. The analysis also reveals when simplified versions of the matched filter can be used.
