KOBE, Japan -- October 18, 2012

FUJITSU TEN LIMITED (Head office: Kobe City, Hyogo, President & Representative
Director: Takashi Shigematsu, Capital:¥5.3 billion) has developed "Automotive
Compact 77GHz 3D Electronic Scan Millimeter Wave Radar" that is capable of
detecting an object in three dimensions, including "elevation" range in
addition to distance and azimuth range.
While making further improvements, FUJITSU TEN will aim at delivering this
product to automobile manufacturers from 2014.
This product will be presented in a paper at the "19^th ITS World Congress
Vienna, Austria" (October 22 (Mon.) – 26 (Fri.), 2012) and will be on display
in the attached exhibition.

In 1997, FUJITSU TEN succeeded in the world's first^(*1) practical application
of 60GHz millimeter-wave radar for dump trucks. Since 2003, a wide variety of
frontward, rearward, and front-sideward 77GHz millimeter-wave radars have been
developed for passenger cars, and those have been delivered to many automobile
manufacturers.
This developed product is for frontward detection usage. By sensing three
dimensions including elevation range in addition to the conventional distance
and azimuth range, the product can detect signs located above or falling
objects over the road, etc. more reliably. That is, the product can identify
obstacles on the road more reliably from a farther position. Through the
advanced signal processing technology (jointly-developed with FUJITSU
LABORATORIES LTD.^(*2)) and the innovative design of antenna for transmitting
and receiving radio waves, FUJITSU TEN has realized the size fitting in the
palm, as large as the size of our latest 2D electronic scan millimeter-wave
radar. The product can be mounted in a wide range of automobiles from
large-sized automobiles to small-sized automobiles.

[Features of Developed Product]
1. Detection of subjects in 3D including elevation range
By use of the 3D scan including elevation range in addition to the distance
and azimuth range, objects above and below are detectable more reliably. For
example, since the height of the guide sign posted above over the expressway
can be detected, more accurate identification of the object in front of the
automobile becomes possible. Since the obstacles on the road can be identified
more reliably from a farther position, the performance in high-speed area of
pre-crash safety feature^(*3) is improved.

2. Compact size
< Size: equal to our latest 2D electronic-scan-type product >
Through the advanced signal processing technology (jointly-developed with
FUJITSU LABORATORIES LTD.) and the innovative antenna design, FUJITSU TEN has
realized the palm-sized 3D scan radar, as large as the size of our 2D
electronic-scan-type millimeter-wave radar.

3. Simplified automobile mounting
The axis adjustment used to be conducted when mounting the millimeter-wave
radar in the automobile factory can be simplified, which contributes to the
productivity improvement.

[Glossary]
(*1)  According to a FUJITSU TEN survey as of August 1997
(*2)   FUJITSU LABORATORIES LTD. (Head Office: Kawasaki City, Kanagawa,
       President and Representative Director: Tatsuo Tomita)
(*3)   Pre-crash safety feature
      General term for the system designed to reduce damages by the collision
       with a leading automobile, an obstacle, or a pedestrian, etc.
       It calculates the distance and the position to the obstacle by sensors
       such as radar or a camera. When there is a high possibility of
       collision, the system alerts the driver that the danger is imminent by
      sound or by indication, and enhances the braking effect. When the
       collision is unavoidable, the system forcibly brakes the car, or
       tightens seat belts. What is controlled differs depending on each
       automobile manufacturer.
