Fujitsu Ten has developed a compact frequency modulated continuous wave (FMCW) millimeter-wave radar with a scanning function. To get the desired performance, weight and compactness, we integrated the transmitting and receiving antennas, and minimized the number of parts by means of monolithic microwave integrated circuit (MMIC) and analog IC technology. As a result, we were able to add a high speed scan by means of an actuator. We use a digital signal processor (DSP) and software that can correctly recognize multiple targets. We have successfully evaluated the radar's suitability for adaptive cruise control (ACC) by installing it in a test car. This paper describes the technologies used and the results of the evaluation

Importance of detecting obstacles around construction machines increase rapidly. The millimeter-wave radar is the most useful sensor to keep to detect obstacles in the current technologies. because of its good performance under severe conditions. The signal processing algorithm of this radar is developed, for the using in working conditions by means of eliminating signal fluctuations and instabilities caused by its environments. The developed millimeter-wave radar has a reasonable performance, for example, detecting the rear side of automobiles and many types of construction machinery from the distance of 100m.
