Abstract： High-resolution reconstruction techniques are investigated for Hai Yang-2Scatterometer(HY2-SCAT)backscatter measurements for a variety of application purposes including land and polar ice detection and the studies of cryophere and biosphere.Three resolution enhancement algorithms,including Additive Algebraic Reconstruction Technique (AART),Multiplicative Algebraic Reconstruction Technique(MART)and Scatterometer Image Reconstruction(SIR),are compared by simulation approach.The results that SIR has the best performance in noise suppression and resolution enhancement of the backscatter measurements than AART and MART algorithms.This study is verified using HY2-SCAT Level-1B(L1B)backscatter measurements.The sigma~0 measurements over some sites with particular backscattering characteristics(e.g.islands)are reconstructed.
