Ionospheric Sounding Based on Spaceborne PolSAR in P-Band

Wulong Guo et al.

Summary: This paper investigates the ability of the P-band SAR system in ionospheric one-dimensional and two-dimensional detection and compares it with the L-band. The study finds that the P-band TEC retrieval is approximately twice as accurate as the L-band retrieval and possesses excellent robustness. In addition, the P-band SAR has higher accuracy in correcting the ionosonde's topside electron density compared to the L-band SAR.
