A Solution for Removing Automotive Radar Interference: Radar Communications

Paper in proceeding, 2018

Automotive radar is becoming an indispensable equipment in modern cars, for different functions including lane keeping,
speed control and parking, especially due to its immunity to bad weather conditions [1]. Likewise, vehicle-to-vehicle
(V2V) communication is on the way to become a standard, having proven its value in dissemination of safety critical information
[2]. However, the widespread use of both technologies lead to problems, cutting short future plans for autonomous
driving and safety. Increased penetration rate and density of automotive radars lead to increased mutual interference, which
in turn result with reduced detection probability and ghost detections [3]. Similarly, Omni-directional V2V communication
transmissions result in high interference with an increased number of vehicles [4]. This interference leads to packet losses,
especially in emergency situations when many vehicles emit warning messages, in turn affecting system-wide safety.
