Chirp signal function
Web# NOT RUN {ch <- chirp(seq(0, 0.6, len= 5000)) plot(ch, type = "l") # Shows a quadratic chirp of 400 Hz at t=0 and 100 Hz at t=10 # Time goes from -2 to 15 seconds. … WebThe OFDM chirp waveform is widely applied in MIMO radar because of its high range resolution and good Doppler tolerance. However, some high lobes exist in the signals’ cross-correlation function for multiplexing of bandwidth and since the signal is based on a chirp signal, high sidelobes also exist in its autocorrelation function.
