Chirp fmcw
WebChirp waveforms are commonly used in automotive radar and other sensor applications to provide the required information for calculating range and Doppler velocity of objects in a scene from the radar returns. An example is a frequency modulated continuous wave (FMCW) radar, which transmits a sequence of chirps within a frame as shown in Figure 1. WebJul 7, 2024 · An FMCW chirp consists of an electromagnetic wave that’s ramped up in frequency linearly over a period in time. These signals are transmitted and reflected by objects and received. In general, an FMCW transmitted chirp can be expressed as: x (t) = Ac * cos ( (wc + Ab * t) * t) (1)
