More Information
Summary:By changing the direction of a detection radio-wave beam within a detection-angle range and by detecting reflected-signal intensities, wherein each of the reflected-signal intensities is detected for each predetermined unit angle, moving averages of the reflected-signal intensities are calculated by using an angular width predetermined for a given distance as an average width. Thus, data of a reflected-signal-intensity distribution is obtained. Accordingly, the direction of a target is detected by finding the direction of the highest reflected-signal intensity.
