A Method to Prevent Target Misdetection in DS-SS Radar
Millimeter wave radar sensors for monitoring the environment around the vehicle are likely to be installed in a growing number of vehicles as intelligent transport systems (ITS) become more sophisticated. However, one possible concern is the generation of misdetection due to radio wave interference between radar systems. To address this issue, development is focusing on radar that uses the direct sequence spread spectrum (DS-SS) modulation protocol, which is capable of allocating a different code to each radar system. However, increasing the number of codes available for use by this protocol makes it difficult to avoid some codes with poor autocorrelation. The quality of code autocorrelation is expressed as range sidelobes of the radar output, which have a major impact on target detection performance. This paper proposes a method to improve target detection performance by reducing the impact of code autocorrelation sidelobes in the case of DS-SS radar output that uses codes with poor autocorrelation. The results of an experiment using the proposed method are also described below.
