Stepped-FM Pulse Radar for Vehicular Collision Avoidance

摘要

In this paper a stepped-FM pulse radar for vehicular collision avoidance is proposed, providing anti-interference capability and high range resolution. Wide-band VCO de- vices have in general a linearity error over the bandwidth, which is critical issue of high-range-resolution radar. We also suggest a compensation scheme based on the LMS method for the VCO linearity error.
