Abstract

This report describes the results of a theoretical investigation of the impacts of non-ideal transionospheric signal propagation on the imaging performance of space-based synthetic aperture radars (SARs). The nature and magnitude of the effects are demonstrated in quantitative terms versus the strength of the ionospheric disturbance. A number of different mitigation schemes for combatting the effects are also evaluated, including: optimal flight and viewing geometry, increased carrier frequency, and adaptive signal processing.
