WebSep 30, 2024 · FMCW Radar. Automotive radar systems operate using a so-called Frequency Modulated Continuous Wave (FMCW). The system transmits a continuous wave at a certain frequency, which is then modulated over a period of time T. This gives the transmitted signal a “time stamp". The signal travels then to the target and part of it is … WebFeb 9, 2024 · This article focuses on amplitude-modulated continuous-wave (AMCW) time-of-flight (ToF), which, because of its robustness and stability properties, is the most common form of iToF. The figures of merit that drive iToF performance are explained and plotted, and system parameters that drive a camera’s final performance are summarized.
