Patent ID: 8300500

Claim:
A detection device, comprising: a transceiving module for periodically transmitting a detection pulse signal toward a space and receiving a reflection wave from a target object as a reception signal; a signal loading module for generating a distance section row by dividing a given detection distance range into a plurality of distance sections, obtaining reception data by sequentially sampling the reception signal for every distance section, and storing the reception signal in a memory; and an interference processing module for sequentially performing interference removal processing for the reception data of each of the distance sections stored in the memory; wherein the interference processing module includes: an interference wave determination module for determining for every distance section whether the reception data of the distance section row including a target distance section is resulting from an interference wave; a signal generating module, if the reception data is determined to be resulting from the interference wave for generating data to be displayed based on one or more reception data other than the reception data in proximity to the reception data at least either in a distance direction or a transmission cycle direction, and if the reception data is determined to be resulting from the reflection wave, for using the reception data as the data to be displayed; and a display module for displaying the data to be displayed.
