Abstract
A radar sensing system for a vehicle includes a transmitter and a receiver. The transmitter is configured for installation and use on a vehicle. The transmitter is configured to transmit radio signals. The receiver is configured for installation and use on the vehicle. The receiver is configured to receive radio signals that include (i) the transmitted radio signals transmitted by the transmitter and reflected from objects in an environment, and (ii) other radio signals that include radio signals transmitted by at least one other radar sensing system. The receiver is configured to filter frequency modulated continuous wave (FMCW) radio signals from the received radio signals to produce filtered radio signals. The receiver is further configured to select between (i) the filtered radio signals, and (ii) the received radio signals before filtering. The filtered radio signals are selected when the other radio signals include FMCW radio signals.
