The letters stand for <strong>frequency-modulated continuous wave</strong>, which describes exactly what the transmitter does: it keeps radiating a signal without pause, and it changes the frequency of that signal over time in a controlled, repeating pattern.</p> <p>That simple idea has big consequences. Because an FMCW radar measures targets by comparing frequencies rather than timing separated pulses, it can deliver very fine range resolution with modest transmit power, see objects at extremely short distances, and estimate range and velocity in the same measurement chain. These properties make FMCW a natural fit for automotive sensing, industrial level measurement, presence detection, and — increasingly — low-altitude security and counter-drone surveillance.</p>
