TARGET DETECTOR AND TARGET DETECTION METHOD FOR DETECTING TARGET USING RADAR WAVES
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...

| description | 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. |
