Abstract
A radar system for a vehicle includes a transmitter, a receiver, and an interference mitigator. The transmitter transmits radio signals. The receiver receives radio signals. The received radio signals include transmitted radio signals reflected from objects. The receiver also processes the received radio signals to produce a sample stream. The interference mitigator successively (i) generates respective signals corresponding to the transmitted radio signals that are reflected from each of a plurality of objects, and (ii) adds the respective signals to the sample stream to form a modified sample stream. The addition of the respective signals removes interference from the sample stream due to the transmitted radio signals reflected from the plurality of objects. The receiver is configured to use the modified sample stream to detect a first object at a first range which is more distant than respective ranges of the plurality of objects.
