Chirp ramp time

Websettings such as resolution bandwidth (RBW) and sweep time. The typically used signal type in automotive radar is a linear frequency ramp modulation (chirp). The important parameters for level measurements of this signal type are the frequency deviation and the chirp rate or chirp length. WebFigure 1: Electric field of a strongly up-chirped pulse, where the instantaneous frequency grows with time. A pulse can acquire a chirp e.g. during propagation in a transparent medium due to the effects of …
