Difference between fmcw radar and uwb radar
WebAn FMCW radar system transmits a chirp signal and captures the signals reflected by objects in its path. Figure 3 represents a simplified block diagram of the main RF components of a FMCW radar. The radar operates as follows: • A synthesizer (synth) generates a chirp. • The chirp is transmitted by a transmit antenna (TX ant).
