Abstract
In order to achieve object detection that does not detect an object moving at a speed within a prescribed speed range, the present invention comprises at least two cross-correlation calculation units which each calculate a cross correlation function between a waveform of a reflection signal obtained when a transmission signal having changing frequencies is reflected by a target object, and a different correlation waveform generated from the waveform of the transmission signal, and a synthesis unit that synthesizes at least two cross-correlation functions from at least the two cross-correlation calculation units so as to make detection of a target object moving at a speed within the prescribed speed range less likely, and that outputs the synthesis results to a post-processing unit.
