Abstract
A shared radar and communication system for a vehicle includes capabilities for radar detection and communication with vehicles equipped with similar systems. A transmitter transmits a modulated radio signal that is modulated based upon at least one of a first spreading code and a second spreading code. The second spreading code is defined by a first plurality of information bits. A receiver receives radio signals that include the transmitted radio signals transmitted by the transmitter and reflected from objects in an environment. A control unit is configured to select the first plurality of information bits. The selection of the information bits encodes selected information for transmission via the transmitted modulated radio signal to be received by another radar sensing system.
