The FMCW is a continuous-based radar frequency modulated (). Unlike traditional pulse radar, the FMCW continuously emits a series of continuous signals with gradually changing frequencies, while simultaneously receiving reflected signals. By analyzing the received signals, parameters such as distance, speed and angle can be measured. Distance & Speed Detection: The C4001 millimeter wave presence sensor (25m) uses frequency modulated continuous modulation (FMCW) to measure distance and speed. It has a maximum measuring range of 25 meters for distance and a speed measurement range of 0.1 to 10 meters per second. Compared with traditional pulse radar technology, FMCW radar can continuously measure the distance of objects. By using the effect you can also get information about the speed of targets. This makes it ideal for applications that require monitoring the motion status of targets. Compared to other types of presence sensors, such as infrared and ultrasonic, the presence sensor C4001 millimeter waves (25 meters) has the advantage to be able to detect both static and moving objects. In addition, it has a relatively strong anti-interference ability, which makes it less susceptible to factors such as temperature changes, ambient light variations and ambient noise. In addition, the FMCW radar can perform continuous frequency scanning, which provides a measurement resolution. By not waiting for the return of the echo signal, it is ideal for applications that require real-time goal monitoring and tracking.
