Abstract :
We have studied using C-band one-dimensional helicopter scatterometer data dependence between distance l and standard deviation (std) and correlation length L for the Baltic Sea ice backscattering coefficient (sigmadeg). The results indicate strong linear dependence between l and L and between In(l) and In(std(sigmadeg)) at least up to distance of few kilometers. This suggests fractal-like behavior for the variation of the Baltic Sea ice sigmadeg as a function of l. The regression coefficients describing the dependencies of l vs. L and In(l) vs. In(std(sigmadeg)) do not discriminate various ice types better than just mean and standard deviation of sigmadeg
