Abstract
This work asses a way to improve the detection of pedestrians, workers or cyclists, but also other static elements on the road. These elements due to its low radar cross-section can be masked by other larger objects close to them, when they are illuminated by an automotive radar. Rotating backscatter is proposed to enhance the detection with automotive FMCW radars due to the introduction of a differentiable micro-Doppler signature. A comprehensive theory of operation is explained in this paper. Simulated and experimental results are presented at 24 GHz for transponder detection in presence of strong clutter in range-velocity maps.
