Abstract

Polarimetric backscatter measurements has potential benefits to improve wind retrieval performance [1]. It simultaneously measures co-polarized backscatter coefficient (σ_hh, σ_vv) and the correlation coefficient of the co- and cross-polarized component (σ_vhhh, σ_hvvv) of radar returns. A pre-processing design of spaceborne polarimetric scatterometer will be introduce in this paper considering to improve the resolution by range filtering [2]. A corresponding formulation for assessing the variance of the measurements due to fading and the thermal noise is presented considering the factors affecting the measurement accuracy.
