FMCW is a radar system based on Frequency Modulated Continuous Wave. Unlike traditional pulse radar, FMCW radar continuously emits a series of continuous wave signals with gradually changing frequencies while simultaneously receiving the reflected signals. By analyzing the received signals, measurements of parameters such as distance, velocity, and angle can be achieved. Distance and velocity detection: The C4001 (25m) millimeter-wave presence sensor utilizes Frequency Modulated Continuous Wave (FMCW) modulation for distance and speed measurement. It has a maximum measurement range of 25 meters for distance and a speed measurement range of 0.1 to 10 meters per second. Compared to other types of presence sensors such as infrared sensors and ultrasonic sensors,the C4001(25m) millimeter-wave presence sensor has the advantage of being to detect both static and moving objects.It also has a relatively strong anti-interference ability,making it less susceptible to factors such as temperature changes,variations in ambient light,and environmental noise.Whether a person is sitting, sleeping,or in motion,the sensor can quickly and sensitively detect their presence. Compared to traditional pulse radar technology, FMCW radar can continuously measure the distance of objects. By utilizing the effect, it can also obtain velocity information of the target objects. This makes it suitable for applications that require monitoring the motion status of target objects. Additionally, FMCW radar can achieve continuous frequency scanning, providing higher measurement resolution. Since it doesn't need to wait for the signal to return, it is suitable for applications that require real-time monitoring and tracking of target objects.
