WebThe chirp time of fast chirp modulation typically ranges less than 100μs. It is a few percent of the modulation time of conventional FWCW automotive Radar. It is difficult to realize such short period of PLL with conventional semi-conductor technology. Open loop configuration eliminates the limitation of PLL, but a high speed ADC is required. WebJul 25, 2014 · The frequency of the chirp signal varies with time, hence the amplitude of each frequency component does not stay the same. To have a same amplitude for all frequencies, the signal needs to have 1 complete cycle for each frequency component.
