Abstract
Provided is a device for detecting intruding objects that enables the detection of intruding objects without requiring antenna switching. Delay units () use different delay amounts to delay signals received at each of a plurality of antennas (). A signal synthesis unit () synthesizes the delayed signals. A frequency conversion unit () converts the synthesized signal frequency to a baseband. A wave detection unit () detects the signal that has undergone frequency conversion. A radar profile generation unit () uses the detected signal to generate a profile formed from the distance from the antenna, and the signal strength at each distance from the antenna. A detection processing unit () detects a peak in the profile at which the signal strength exceeds a preset threshold value, and determines whether an intruding object is present in a detection region on the basis of the detected peak.
