KARIYA, Japan, Nov. 20, 2012 /PRNewswire/ -- DENSO Corporation has developed a new and higher-performing millimeter-wave radar that has a longer and wider detection range, which helps improve the responsiveness of an active safety technology, such as Pre-crash Safety (PCS) and Adaptive Cruise Control (ACC) systems. DENSO's new, multi-zone radar is significantly lower in cost due to an improved material selection and also is approximately the same size as the company's previous model. The new millimeter-wave radar system is available as a factory option on the Mazda6, which launched first in North America and then in Japan, Europe and other regions this past fall.

"The wider radar detection is especially important in the United States where we are a nation of multiple lane highways." Achieving a Higher and Wider Detection AngleDENSO's new radar has a detection distance of 205 meters and a +/- 18 degree detection radius within a distance of 35 meters from the vehicle. This is compared to 151 meters and +/- 10 degrees in the conventional product. To achieve a longer detection distance, DENSO improved the electronic circuit design in a way that reduces electromagnetic interference that could limit the receiver's detection of reflected radio waves. This allows the sensor to have an enhanced receiving ability for objects at a longer distance. This longer detection range enables ACC-equipped vehicles to maintain a safe and constant distance to the vehicles in front of them – even when traveling at higher speeds. Also, by better positioning the receiving antenna, the radar has a wider detection angle, which improves system responsiveness.
