Claim Text:
1. A detection device, comprising: a transceiver configured to transmit a transmission signal and receive an echo caused by the transmission signal to output a measurement according to an intensity of the echo, wherein the measurement includes a plurality of reception signals; and an interference detector configured to detect interference signals from the plurality of reception signals associated with one measurement, perform first interference detection processing having a first interference detection sensitivity upon detecting that a number of the reception signals from the one measurement detected as the interference signals is greater than zero and below a predetermined threshold, and perform a switching operation of switching between the first interference detection processing and second interference detection processing that has a second interference detection sensitivity higher than the first interference detection sensitivity used in the first interference detection processing upon detecting that the number of the reception signals from the one measurement detected as the interference signals is at least equal to the predetermined threshold.
