摘要：

PROBLEM TO BE SOLVED: To propose a new method for correlation integration processing, different from conventional methods.SOLUTION: In a base band processing circuit part 20, a Doppler compensation circuit 215 delays a replica code by a shift amount by which a peak phase of a correlation operation result by a correlation operation part 23 is shifted due to Doppler, in a given integration time interval. The correlation operation part 23 performs correlation operation between a received signal by an RF receiving circuit part and the replica code delayed at the Doppler compensation circuit 215. An integration part 24 integrates the correlation operation result by the correlation operation part 23, in the integration time interval.
