Frequency Modulated Continuous Wave (FMCW)

Frequency Modulated Continuous Wave (FMCW) is a radar technology that continuously emits radio waves whose frequency varies over time in a predictable pattern. When these waves hit an object, they bounce back to the radar. By comparing the frequency difference between the sent and received signals, the system can determine how far away the object is. FMCW is used in various applications like automotive collision avoidance and drone navigation because it provides accurate distance measurements and works well in different weather conditions, all while maintaining a constant signal transmission for high-resolution detection.
