Abstract
A method of performing vibrational radar backscatter communications includes transmitting radar waveforms at millimeter wave frequencies, receiving, from a vibrating transponder, vibrational backscatter of radar waveforms, performing synchronization on the vibrational backscatter to determine a start of an encoded communication message sequence, calculating a predicted symbol sequence based on the encoded communication message sequence, identifying, from one or more predetermined messages, an actionable message from the predicted symbol sequence, and communicating the actionable message to a display of a vehicle or causing the vehicle to take an action. This method can also be performed on a computing system that includes a processor, memory, and instructions stored in the memory and the method can be stored on computer readable storage media.
