=== What You Will Learn ===
In this tutorial you will use [[RF.Spice]]'s black-box virtual blocks to model a Quadrature Amplitude Modulation (QAM) communication an FMCW radar system . You will explore FMCW radar systems with both sawtooth and construct a pair of transmitter triangular chirp modulations and receiver circuits. Then you will use a long lossy transmission line as see how the channel to connect the transmitter target range and receiver circuits. You will simulate velocity information are extracted from the transmission of a binary data packet through this communication linkoutput beat signals.
