WebChirp signal, with frequency as a function of time. An 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. WebAbstract—This paper proposes a fast and accurate chirp-rate estimation algorithm in noisy environment. The proposed method searches the inverse maximum magnitude of the angle-sweep fractional Fourier domain and finds the optimum angle, which provides an estimate for the chirp-rate.
