摘要： The synthetic-aperture-radar signal processing device pertaining to the present invention is provided with a low-precision interpolation processing unit for performing interpolation processing of discrete data obtained from a synthetic-aperture radar reception signal, a high-precision interpolation processing unit for performing interpolation processing of discrete data at a higher precision than the low-precision interpolation processing unit, a curvature assessment unit for selecting either the high-precision interpolation processing unit or the low-precision interpolation processing unit in accordance with a first curvature which is a curvature of the discrete data in a subject region for interpolation processing, and an image reproduction processing unit for reproducing an image using the result of interpolation processing selected by the curvature assessment unit, the curvature assessment unit selecting discrete data points A, B, and C arranged adjacent to each other in a predetermined direction in the vicinity of the subject region and determining the first curvature on the basis of the distance ?f1R between point C and the point externally dividing a line segment connecting points A and B so that (AB + BC):BC (where AB is the distance between points A and B, and BC is the distance between points B and C). Through this configuration, the computational load during calculation of a curvature from discrete data can be reduced.
