Chirp signal function

WebChirp. Like noise, it is sometimes useful to play a chirp signal against a receiver. One of the gnuradio tutorials does this in a clean way using a probe. The probe follows a triangle wave level and modifies a sine wave's frequency with that value. As a learning exercise, I wanted to incorporate custom code in gnuradio.

WebThe time signal for a long LFM chirp is viewed by plotting the signal along successive rows. Each row covers 60 milliseconds, so only the first quarter of the signal is shown. … 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.

WebOct 14, 2024 · A chirp, or swept sine signal can be expressed: x(t) = A(t) sin (2πɸ (t)), where ɸ is the phase, A is the amplitude, and t is the time. Most research has been done using linear or logarithmic chirp signals. Linear chirp signals provide equal energy stimulus at all frequencies, while the energy of a logarithmic chirp decreases with frequency.
