Furukawa Automotive Systems Inc. (Headquarters: Inukami-gun, Shiga Prefecture; President: Shigenobu Abe), a member of the milan米兰体育官网, has verified that “24 GHz perimeter monitoring radars” can be used for fixed infrastructure applications. These radars are essential components of the advanced driver assistance systems (ADAS) used for automobile safety. Furukawa Automotive Systems Inc. has developed a technology to ensure a sufficient observational range for pedestrians, vehicles, and other objects, based on signal processing technologies developed for vehicle-mounted radars.

The world is waiting for the arrival of a totally safe motorized society free from traffic accidents. This is expected to become a reality in the near future through use of such technologies as self-driving automobiles, CASE, and MaaS. Vehicle safety has always been a concern since the first automobiles were introduced, but society now faces the increasingly common danger of drivers driving in the wrong direction on highways. The Ministry of Land, Infrastructure, Transport and Tourism has also considered infrastructures to prevent accidents in accident-prone areas on public roads in its “Traffic Accident Elimination Plan (Strategic Elimination of Risky Accident Areas).” milan米兰体育官网 has investigated using its vehicle-mounted radar technology, which leverages the strengths of the Furukawa pulse system to detect objects at a wide angle and wide range in various environment, for use in preventing traffic accidents in addition for use in systems to detect vehicles traveling in the wrong direction.

A vehicle-mounted radar is installed just above ground level (around 50 cm to 90 cm) in order to monitor the perimeter around the vehicle. This allows it to detect a wide range in the horizontal direction (±60° or more). (Refer to Attachment [1]).
In contrast, radars used for infrastructure are often installed aimed downward at an angle over the area they are monitoring (as shown in Attachment [2]), requiring that they be installed at an appropriate height, tilt angle, and distance from the road. There are also other issues involved with using the technology for infrastructure applications, such as the effect of strong reflections from approaching structures and the risk of sensors being blocked by crossing objects. However, by applying signal processing technologies developed over many years for vehicle-mounted radars together with the Furukawa system (pulse system; see Attachment [3]), milan米兰体育官网 has developed technology that offers excellent environmental resistance, ensures a sufficient observational range, and is capable of wide-angle monitoring to individually detect multiple obstacles, people, and road signs. This technology is expected to be used on fixed infrastructures such as systems used to determine traffic conditions on intersections and other accident-prone roads.

1. Detects the position, speed, and direction of moving objects. The milan米兰体育官网 pulse system detects distance and relative speed on two axes (time and frequency), allowing multiple targets such as obstacles, people, and road signs to be individually detected at a wide angle (±60° or more) and over a wide range (0 to 75 m).
2. Capable of detecting objects in complicated situations.
The technology can detect a faraway object even if there is a sign or other large reflective object nearby.
3. As shown in the chart in Attachment [4], the technology is not easily affected by weather conditions (rain, snow, fog), changes in brightness (day, night, backlight), milan米兰体育官网.
4. Image diagnosis using cameras requires a complicated system that includes image processing. In contrast, this technology is capable of directly processing signals from the radar itself, resulting in a simpler system to operate.
