A drive support device includes: an acquisition processing unit that acquires (i) a distance to an object detected based on a result of transmission of a transmission wave and reception of a reception wave that is the transmission wave having returned upon reflection by the object and (ii) a reception level of the reception wave used to detect the distance; and a detection processing unit that detects information about a height of the object, based on a relationship between the distance and the reception level that are acquired by the acquisition processing unit.

Drive support device

An object detection device includes: a transmitter transmitting a transmission wave to an outside including a road surface; a receiver receiving a reflected wave of the transmission wave being reflected by an object as a reception wave; a CFAR processor acquiring 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 estimating 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.
