| 摘要 |
The invention provides a signal process apparatus for an on-vehicle radar and a method thereof that can reduce operation load and obtain a sufficient detection capability.According to information on a detected object, the invention registers as peak data a frequency BIN contained in a frequency region around a prediction peak that is to be detected on a distance power spectrum. The invention predicts a running line on which a predetermined vehicle runs, obtains a power spectrum along the running line, and registers as peak data the peak of the power spectrum. Then, the invention averages the distance power spectrum obtained for each channel, registers as peak data the peak of the averaged distance power spectrum, and only with regard to the registered peak data (frequency BIN), seeks a directional power spectrum.
