An Imaging Compensation Scheme for Correcting Ionospheric Effect on High-Resolution Spaceborne P-Band SAR

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

High-resolution spaceborne P-band SAR has broad prospects in the future due to its penetrating capabilities. However, conventional imaging methods are no longer suitable for high-resolution P-band SAR because of ionospheric effects including dispersion and scintillation. In this paper, an imaging compensation scheme with modified Chirp Scaling (CS) has been proposed, correcting ionospheric effects by a new spectrum segmentation method and Phase Gradient Autofocus (PGA). The effectiveness of the proposed compensation scheme for high-resolution P-band SAR has been verified by point target and scene simulation with ALOS-PALSAR data.
