Chirp frequency spectrum

WebOct 20, 2014 · The chirp signal is useful for the radar, because it can be generated by simple liner FM pulse which can increase the frequency bandwidth of pulse and accordingly improve the accuracy of range measurement. Moreover, the chirp signals (LFM or NLFM) have satisfied properties of ambiguity function for radar application. WebLoRa is a wireless modulation technique derived from Chirp Spread Spectrum (CSS) technology. It encodes information on radio waves using chirp pulses - similar to the way dolphins and bats communicate! LoRa modulated transmission is robust against disturbances and can be received across great distances.
