Chirp sweep frequency
Weby = chirp (t,f0,t1,f1) generates samples of a linear swept-frequency cosine signal at the time instances defined in array t, where f0 is the instantaneous frequency at time 0, and f1 is the instantaneous frequency at time t1. f0 and f1 are both in hertz. If unspecified, f0 is 0, t1 is 1, and f1 is 100.

Webfrequency, andT the duration of the chirp. This signal is shown in Figure 2. The explanation of its special property willcome in ection 4, when theS -1.0 signal is analyzed. The variable speed chirp’s special property comes from the simple idea ofusing the speed of the sweep to control the frequency response [3]. The WebIt has four types of signal generators as follows, and can generate sine wave signal, frequency sweep, chirp signal, colored noise with octave-band noise. - Sine wave generator: It includes sine wave generator that generates a pure tone with a high precision of DVD quality and a frequency accuracy of 0.1Hz, and sets a frequency by 4 presets …

The output is essentially a passband modulated signal. What if I want to see the chirp in baseband?
WebFMCW signal transmits a narrowband signal whose carrier frequency changes linearly with time for each sweep. The green line represents the transmitted signal where the frequency increases from f0 till fx(T), where T is the duration of one sweep or chirp (chirp duration). The figure shows 2 sweeps.
