Abstract

Real Aperture Radar (RAR) remains a fundamental tool for oceanographic observations and surface wind retrieval. A critical component of this analysis is the "HH" polarization state—where both the transmitted and received signals are horizontally polarized. This paper explores the computational representation of these signals often found in datasets distributed via compressed archives (e.g., HH.rar ). File: HH.rar ...

This paper investigates the signal processing techniques used to extract geophysical information from data. Unlike Synthetic Aperture Radar (SAR), Real Aperture Radar (RAR) provides unique challenges in spatial resolution and azimuthal cutoff. We analyze the mathematical models used to represent HH (Horizontal-Horizontal) polarimetric images, focusing on their sensitivity to surface roughness and permittivity gradients at the sea-air interface. 1.
