Abstract: A radar image processing device includes at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: determine a search range based on a reference block and a layover direction, the reference block being set as an area of interest in a radar image generated from data obtained by an imaging radar, the layover direction being a direction in which layover occurs in the radar image and being estimated from an incident direction of an electromagnetic wave used for observation by the imaging radar; extract a similar block that is similar to the reference block and included in the search range by searching the search range; and perform filtering processing for reducing speckles generated in the radar image by using the reference block and the extracted similar block.

Abstract: An information processing device according to one aspect of the present invention includes at least one memory storing instructions; and at least one processor coupled to the memory and configured to execute the instructions to: extract a candidate point which is a point contributing to a signal at a target point, based on a position of the target point in a three-dimensional space and a shape of an observed object, the target point being a point specified in an intensity map of the signal from the observed object, the intensity map being acquired by a radar; and generate an image indicating a position of the candidate point in a spatial image capturing the observed object.

Abstract: This information processing device is provided with: a candidate point extraction unit for extracting, on the basis of the position in three-dimensional space of a target point specified in an intensity map of a signal from an observed object acquired through radar and the shape of the observed object, a candidate point that contributes to the signal at the target point; an evaluation unit for evaluating the reliability of the candidate point in terms of signal analysis on the basis of geographic information indicating the state of a surface including the candidate point; and an output unit for outputting information indicating the result of the evaluation.
