Abstract

A radar system including a transmitter configured for installation and use with the radar system and configured to transmit radio signals. The transmitted radio signals are defined by a spreading code. The radar system also includes a receiver configured for installation and use with the radar system and configured to receive radio signals that include transmitted radio signals transmitted by the transmitter and reflected from objects in an environment. The receiver is configured to convert the received radio signals into frequency domain received samples. The receiver is also configured to correlate the frequency domain received samples to detect object distance.
