Abstract: An object detection device includes an acquisition circuit, a calculation circuit, and an estimation circuit. The acquisition circuit acquires elapsed times from when an ultrasonic wave is transmitted from a transmission microphone to when reception microphones each receive the ultrasonic wave. The calculation circuit calculates a wind speed on the basis of the elapsed times acquired by the acquisition circuit. The estimation circuit estimates a vehicle state on the basis of the wind speed calculated by the calculation circuit.

Abstract: A radar device employs a configuration provided with: a receiver which, in operation, receives one or more radar transmission signals transmitted from another radar device, in an interference measurement segment in which transmission of a radar transmission signal from the radar device is stopped; A/D conversion circuitry which, in operation, converts the one or more radar transmission signals from the other radar device received by the receiver from one or more analog signals into one or more digital signals; and an interference detection circuitry which, in operation, performs a correlation calculation between each of one or more discrete samples that is the one or more digital signals and a prescribed coefficient sequence to detect one or more prescribed frequency components included in the one or more digital signals, as one or more interference signal components.

Abstract: A ranging device includes transducers, a transmission circuit, a reception circuit, a transfer data generation circuit, and a transfer circuit. The transmission circuit causes the transducers to transmit transmission waves. The reception circuit outputs a received signal obtained by digitizing a reflected wave of the transmission wave with a sampling frequency equal to or more than a frequency of the transmission wave. The generation circuit separates, into a target period and a non-target period, time-series received signals. The target period is a period in which a wave height is equal to or more than a threshold. The non-target period is a period in which a wave height is less than the threshold. The generation circuit performs thinning-out processing on received signals in the non-target period and generates waveform information indicating a waveform received by the transducer. The transfer circuit outputs the waveform information.
