摘要：
Global navigation satellite systems reflectometry (GNSS-R) involves making measurements from the reflections from the Earth of navigation signals from GNSS. In this paper, a resolution enhancement technique based on the Truncated Singular Value Decomposition (TSVD) approach is described to obtain a given spatial resolution in the Normalized radar Cross Section (NRCS) images from GNSS-R's Delay-Doppler Maps (DDMs). The ocean target information contained in the DDMs obtained by the GNSS-R instrument aboard the British TechDemoSat-1 (TDS-1) satellite have been inverted by using the proposed method. Experiment show the robustness of the approach that results in satisfactory reconstruction performance.
