Abstract
In an object detection device, a signal generation unit generates a drive signal, a transmission unit transmits an ultrasonic wave as a search wave in response to the input drive signal, and a reception unit receives an ultrasonic wave to generate a received signal. A judging unit performs object detection determination based on the received signal. The drive signal has at least two frequencies, and the judging unit extracts at least two amplitudes corresponding to the at least two frequencies from the received signal, and performs determination based on a relationship between the at least two amplitudes.
