Chirp processing
http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/signal/chirp.html WebApr 11, 2024 · Dechirp refers to the process of converting the LFM signal from different scatter points (shown in the upper right corner of Fig. 2) to a single-frequency signal (shown in the lower right corner). The frequency of the single-frequency signal is related to the position information of each scattering point.

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. WebSep 16, 2024 · If your program processes the output of dechirp in other ways, take the mixing order into account." So you're amost there. MATLAB's functions account for this so you need to account for the change yourself when doing the manual range-Doppler map.

Clearly, for SNR above about 14.5dB, chirp slope keying performs better than standard phase shift keying in the simulated UWA environment.
