Abstract
A radar system is described that comprises a transmitter and a receiver. The transmitter transmits radio signals. The receiver receives interfering signals due to local signal coupling of transmitted signals. The local signal coupling comprises at least one interfering path or mechanism. The receiver is configured to output a replica of each of the interfering signals. Each replica is configured to replicate a particular interfering signal received. The receiver is configured to combine into a signal path a replica of an interfering signal to subtract the interfering signal from the signal path. The receiver receives the transmitted radio signals transmitted by the transmitter and reflected from objects in an environment without saturating the signal path due to the subtraction of the interfering signal from the signal path.
