Claim 0:
1. A ranging device including transducers, the ranging device comprising:
a transmission circuit configured to cause at least one of the transducers to transmit a transmission wave;
a reception circuit configured to output a received signal obtained by digitizing a reflected wave of the transmission wave by using a sampling frequency equal to or more than a frequency of the transmission wave, the reflected wave being received by each of the transducers;
a transfer data generation circuit configured to
separate, into a target period and a non-target period, time-series received signals output from the reception circuit, the target period being a period in which a wave height is equal to or more than a threshold, the non-target period being a period in which a wave height is less than the threshold,
perform thinning-out processing on received signals in the non-target period, and
generate waveform information indicating a waveform received by the transducer; and

a transfer circuit configured to output the waveform information generated by the transfer data generation circuit.
