CHIRP FREQUENCY NON-LINEARITY MITIGATION IN RADAR SYSTEMS

摘要

The disclosure provides a radar apparatus. The radar apparatus includes a transmit unit that generates a first signal in response to a reference clock and a feedback clock. The first signal is scattered by one or more obstacles to generate a second signal. A receive unit receives the second signal and generates N samples corresponding to the second signal. N is an integer. A conditioning circuit is coupled to the transmit unit and the receive unit. The conditioning circuit receives the N samples corresponding to the second signal, and generates N new samples using an error between the feedback clock and the reference clock.

1. A radar apparatus comprising:
a transmit unit configured to generate a first signal in response to a reference clock and a feedback clock, wherein the first signal is scattered by one or more obstacles to generate a second signal; a receive unit configured to receive the second signal and configured to generate N samples corresponding to the second signal, wherein N is an integer; and a conditioning circuit coupled to the transmit unit and the receive unit, the conditioning circuit configured to receive the N samples corresponding to the second signal, and configured to generate N new samples using an error between the feedback clock and the reference clock.
