<p><P>PROBLEM TO BE SOLVED: To prevent an increase in an amount of memory used in scan correlation processing even in the case of improving resolution of a radar image. <P>SOLUTION: A scan correlation processing device comprises: a class selection part for selecting a class corresponding to a most recently calculated output value and a class corresponding to a sweep data value to be input; an instruction storage part for preliminarily storing an instruction table in which an instruction code, which shows an operation for calculating an output value, is associated with each combination of the class to the output value and the class to the sweep data value; an instruction code retrieval part for retrieving an instruction code according to the combination of the class, which is selected by the class selection part and corresponds to the most recently calculated output value, and the class corresponding to the sweep data value to be input; and an operation part for calculating the output value from the most recently calculated output value and the sweep data value to be input, based on the instruction code retrieved by the instruction code retrieval part. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
