ABSTRACT:
A detection device for detecting a body entering a predetermined range has a transmission means for periodically radiating a pulse-like transmission signal by way of an electromagnetic wave to which a band restriction has been applied, a first reception means and a second reception means, and a judgment means. Each of the reception means performs receiving, as a reception signal, the electromagnetic wave reflected by the body, periodic sampling of the reception signal after a predetermined delay time has elapsed from transmission, and judging, based on a result of the periodic sampling, whether the body exists. The judgment means judges, based on judgment results of each of the first reception means and the second reception means, whether the body has entered into the predetermined range, and outputs a judgment result.
