Original Abstract Submitted

example embodiments relate to techniques that involve detecting and mitigating automotive interference. electromagnetic signals propagating in the environment can be received by a radar unit that limits the signals received to a particular angle of arrival with reception antennas that limit the signals received to a particular polarization. filters can be applied to the signals to remove portions that are outside an expected time range and an expected frequency range that depend on radar signal transmission parameters used by the radar unit. in addition, a model representing an expected electromagnetic signal digital representation can be used to remove portions of the signals that are indicative of spikes and plateaus associated with signal interference. a computing device can then generate an environment representation that indicates positions of surfaces relative to the vehicle using the remaining portions of the signals.
