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. WebThe spectrum of a chirp pulse describes its characteristics in terms of its frequency components. This frequency-domain representation is an alternative to the more familiar time-domain waveform, and the two versions are mathematically related by the Fourier transform. The spectrum is of particular interest when pulses are subject to signal ...
