WebSep 15, 2006 · In the simplest binary case, an ‘up’ chirp (i.e., a signal with instantaneous frequency that linearly increases with time) represents a ‘1’ and a ‘down’ chirp … WebMay 18, 2024 · Abstract: In this paper, we investigate two categories of linear frequency-modulated chirp signals suitable for single-photodiode based coherent light detection and ranging (LiDAR) systems, namely, the frequency-modulated continuous-wave (FMCW) single-sideband (SSB) signal and the amplitude-modulated double-sideband (DSB) … WebThe experimental results show that the chirp signal improves the signal-to-noise ratio and expands the applicable time-of-flight algorithm. The waveform pulse width after cross-correlation is 1.5 μs, compared with 40 μs before. The time-of-flight uncertainty can achieve 1.03 ns compared to 8.6 ns before. cynthia moody reading ma
