Title:
SIGNAL PROCESSING DEVICE AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/181018
Kind Code:
A1
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.
