Abstract
An obstacle detection device according to the present disclosure includes: a transmission circuit, which, in operation, transmits a transmitted wave signal subjected to frequency modulation; a reception circuit, which, in operation, receives a signal externally; an object detection circuit, which, in operation, detects an object existing in a wave transmission direction of the transmitted wave signal, based on a reflected wave of the transmitted wave signal received by the reception circuit; an interference detection circuit, which, in operation, detects, as interference, another transmitted wave signal transmitted from another transmission circuit different from the transmission circuit, based on the signal received by the reception circuit; and a determination circuit, which, in operation, determines a frequency modulation pattern to be applied to the transmitted wave signal and a transmission timing of the transmitted wave signal, based on detection results of the object detection circuit and the interference detection circuit.
