<P>PROBLEM TO BE SOLVED: To provide a radar image processor of high detection precision for a time-serial change of an observation object, even when an area ratio of a range generating the time-serial change to a range of the observation object, within the range, is small. <P>SOLUTION: This processor calculates a correlation value between respective partial images corresponding to the prescribed range of the observation object in two radar images of the observation object acquired in different times by a radar system, predicts a change area that is an area in a range generating the time-serial change between the different times within the prescribed range, to correct the correlation value in response to the area within the prescribed range and the predicted change area, and detects the time-serial change of the observation object generated between the different times within the prescribed range, on the basis of the corrected correlation value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
