Compensating for Groundplane Deformations of a Space-Based Radar to Improve Clutter Cancellation Performance

Abstract

Effects of deformations on the clutter cancellation of a hypothetical large phased-array space-based radar antenna groundplane are described. The radar is assumed to use a displaced-phase-center antenna (DPCA) for cancelling stationary ground clutter. A multilateration method of measuring the deformations is analyzed to determine its effectiveness in compensating for the deformations and improving clutter cancellation. Finally, a data staleness problem inherent in the proposed serial sampling method is described, a potential solution is presented, and its feasibility is discussed.
