Abstract
A radar sensing system for a vehicle includes at least one transmitter, at least one receiver, and a processor. The at least one transmitter is operable to transmit a radio signal at one of a plurality of carrier frequencies. The at least one receiver is operable to receive a radio signal which includes a reflected radio signal that is the transmitted radio signal reflected from an object. The at least one receiver is operable to receive an interfering radio signal transmitted by a transmitter of another radar sensing system. The processor is operable to control the at least one transmitter to selectively transmit radio signals on one of the plurality of carrier frequencies. The processor is further operable to at least one of select a carrier frequency with reduced interference and avoid interference from the other radar sensing system.
