Abstract
A radar sensing system for a vehicle includes a transmitter, a receiver, a processor and an adaptive filter. The transmitter is configured to transmit a radio signal. The receiver is configured to receive radio signals that include the transmitted radio signal reflected from objects in the environment, as well as further including other radio signals transmitted from at least one other radar sensing system. The receiver is further configured to produce a sampled stream. The sampled stream is provided to the processor. The processor, responsive to further processing of the sampled stream, controls the adaptive filter to filter the sampled stream, such that the other radio signals transmitted from the at least one other radar sensing system are removed from the received radio signal.
