Claim 0:
1. An object detection device comprising:
a transmitter configured to transmit a transmission wave to an outside including a road surface;
a receiver configured to receive a reflected wave of the transmission wave being reflected by an object as a reception wave;
a CFAR processor configured to acquire a CFAR signal at a predetermined detection timing by CFAR processing based on a value of a first processing target signal based on a reception wave received at the detection timing and an average value of values of second processing target signals based on the reception waves received in predetermined sections before and after the detection timing; and
an estimator configured to estimate an absorption and attenuation value corresponding to the average value based on a road surface reflection estimation expression that defines a relation between the average value and the absorption and attenuation value in advance.
