Abstract: An on-vehicle target detection apparatus is provided. The apparatus includes a radar sensing portion and a processing unit that processes information from the radar sensing portion. The processing unit detects a target that is present in the periphery of the vehicle based on detection results from the radar sensing portion, and determines a depth determination value indicating the depth of the target detected. The processing unit compares the depth determination threshold and a threshold set in advance and determines that the target is a low-lying target that is surmountable by the vehicle, when the depth determination value is determined to be less than the threshold.

Abstract: A radar device includes a transmitting unit, a receiving unit, and a signal processor. The transmitting unit transmits a radar wave. The receiving unit mixes the received incoming wave with the radar wave to generate a beat signal. The signal processor executes a target detection process to detect a target having reflected the radar wave. In the target detection process, a signal value is extracted from the beat signal generated by the receiving unit for each of specified times, the specified time being a reciprocal of a DC lo component frequency, an approximation curve of a plurality of the signal values is calculated as a DC component signal, and the calculated DC component signal is subtracted from the beat signal to generate a target signal. Based on a result of frequency analysis performed on the target signal, a target that is a source of the incoming wave is detected.
