PROBLEM TO BE SOLVED: To securely prevent occurrence of radio wave interference in an object detection device to be provided in a plurality of coalition instruments.SOLUTION: An object detection device detecting a motion of a detection object or presence or absence thereof comprises: a transmission unit 210 that transmits a transmission wave to a detection area ready for detecting the detection object; a reception unit 220 that receives a reflection wave reflected by the detection object of the detection area; a detection signal creation unit 230 that creates a detection signal on the basis of the transmission wave to be transmitted by the transmission unit 210, and the reflection wave to be received by the reception unit 220; and a determination unit 300 that determines the motion of the detection object or presence or absence thereof on the basis of the detection signal. The determination unit 300 comprises: frequency change means 360 that changes a frequency of the transmission wave on the basis of an external operation instruction; and interference occurrence determination means 350 that determines occurrence of radio wave interference on the basis of the detection signal to be created by the detection signal creation unit 230.SELECTED DRAWING: Figure 3 |
