WebIn semiconductor lasers or amplifiers, chirps can also result from refractive index changes associated with changes in the carrier density. The chirp of a pulse can be removed or reversed by propagating it through optical … WebAug 29, 2024 · A chirp is characterized by the start frequency ( f c), Bandwidth ( B) and duration ( T c). The slope of a chirp defines the rate at which the chirp ramps up. A single target in front of the radar produces an IF signal that is a constant frequency tone, the frequency being given by: d is the distance of the target from the radar in m
WebJun 26, 2012 · Phase is the integral of frequency, so if you have a linear function for frequency (i.e. a constant-rate increase from f1 to f2), then phase will be a quadratic function of time. You can figure out the maths …
