Sumitomo Electric Industries launches pedestrian detector

The company claims this detector has robustness against variable environmental conditions owing to the use of a 24 GHz-band millimeter-wave radar technology

Sumitomo Electric Industries has launched pedestrian detector for driving safety support systems (DSSS) to reduce traffic accidents. The company claims this detector has robustness against variable environmental conditions owing to the use of a 24 GHz-band millimeter-wave radar technology. In addition, it features high accuracy in pedestrian detection enabled by the Company’s proprietary algorithm and a wide detection area.

Main features of the product

  1. Robustness against variable environmental conditions
    The pedestrian detector uses a 24 GHz-band millimeter-wave radar, which is robust against variable environmental conditions such as sunshine in the day and night, as well as clear, rain and other weather conditions.
  2. High detection performance
    The millimeter-wave radar transmits a radio wave and receives its reflection from an object to measure the distance between itself and the object. The algorithm incorporated into the product tracks and predicts the movement of pedestrians by analyzing characteristic information conveyed by the reflected wave. This technique enables the products to detect pedestrians behind passing vehicles.
  3. Wide detection area
    One difficult challenge for a millimeter-wave radar was to achieve incompatible tasks of covering a wide range in close proximity and extending the detectable distance. However, we have developed multiple-channel antennas and a signal processing technique that uses them, enabling a wide detection area for the detector installed on a pedestrian signal pole near the crosswalk. Thus the product detects pedestrians both in the waiting area in close proximity and those on the crosswalk, whether the crosswalk is small or large, as shown.

By offering this product, Sumitomo Electric will continue to contribute to reduced traffic accidents and strive for a safer traffic environment.
