WebMar 31, 2024 · To explain chirp, consider the imaginary system of Fig. 1. Instead of transmitting a single frequency pulse, the radar now transmits, in turn, four discrete frequencies forming the over-all transmitted pulse. The first frequency (f 1) is transmitted for a time T, then frequency f 2 for a time T, then f 3 for time T, and finally f 4 for time T ... WebJan 28, 2024 · The “chirp” signal sweeps smoothly across specific frequency range: usually 125 kHz, 250 kHz or 500 kHz wide. How long the sweep takes to complete is determined by the “spreading factor” (SF)....
