Doppler-Resilient 802.11ad-Based Ultra-Short Range Automotive Radar

We present an ultra-short range automotive radar based on Prouhet-Thue-Morse modified Doppler-resilient Golay sequences embedded in the IEEE 802.11ad preamble. The proposed processing reveals detailed micro-features of common automotive objects verified through extended scattering center models of animated pedestrian, bicycle, and car targets. Numerical experiments show that our approach results in $2.5$% reduction in probability of false alarm at low signal-to-noise-ratios and sidelobe suppression of $20$ dB up to Doppler velocities of $\pm144$ km/h.
