SAR IMAGE ANALYSIS SYSTEM, IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

摘要

This invention is directed to an image processing apparatus that generates an evaluation index of a persistent scatterer likelihood without any influence of a large phase change with respect to a target whose displacement is nonlinear, a target whose elevation is high, or a target whose displacement is large. The image processing apparatus includes a phase array accumulator that accumulates phase arrays of respective pixels over a plurality of images, a clustering unit that classifies the respective pixels into a plurality of clusters based on the phase arrays, and a phase correlation calculator that calculates a correlation between a phase change in each of the plurality of clusters and the phase array at the respective pixels.
