微波雷达
Both microwave radar and millimeter-wave radar detect targets by transmitting high-frequency electromagnetic pulses and then measuring the reflected signals to calculate distance. By adjusting the working frequency and thus changing the wavelength, different radar systems can accurately identify targets of varying sizes and material types.
A microwave radar sensor is especially common in smart lighting, smart security, smart sensor switches, smart bathrooms, smart homes, and other application scenarios. Within a suitable microwave radar range, it can detect motion, slight body movements, and even subtle breathing signals, thus enabling precise presence sensing whether a person is moving or staying still. As a result, modern microwave radar technology not only improves automation and comfort, but also enhances safety and energy efficiency in everyday environments.

Microwave radar is a sensing technology that uses electromagnetic waves at microwave frequencies to detect and analyze the presence, movement, or distance of objects without physical contact. It works by emitting microwave signals and receiving their reflected echoes, allowing the system to calculate parameters such as the target’s distance, speed, and motion characteristics.
Unlike optical or infrared sensors, microwave radar is unaffected by changes in light, dust, or temperature, and can penetrate materials such as wood, plastic, and non-metallic surfaces, enabling reliable detection in complex indoor environments.
In practical applications, microwave radar is widely used in:
– Indoor vital sign detection, such as monitoring human breathing or movement, for security and occupancy awareness;
– Access control and vehicle detection at doorways, for automated door control, traffic gate management, and parking systems;
– Unmanned aerial vehicle (UAV) obstacle avoidance, providing high-precision distance measurement and collision protection;
– Other intelligent sensing scenarios requiring non-contact, real-time detection.
Microwave radar boasts advantages such as high sensitivity, strong environmental adaptability, and reliable performance, making it a key technology for intelligent sensing and intelligent control systems.
Microwaves, with their high frequency and short wavelength, are widely used in radar systems, making them an ideal choice for long-range, high-precision detection and target localization. This characteristic allows microwaves to form narrow beams with extremely high directionality and resolution, enabling radar systems to accurately measure the position, velocity, and shape characteristics of targets.
Furthermore, microwaves possess excellent penetrating power, able to pass through clouds, rain, smoke, and fog, allowing radar to operate stably and reliably under various complex weather and lighting conditions—an advantage difficult to achieve with optical or infrared detection technologies.
Simultaneously, the microwave frequency band is particularly suitable for Doppler measurements, allowing radar to obtain target motion and velocity information by analyzing the frequency shift of reflected signals.
With its advantages of long detection range, high resolution, strong anti-interference capability, and good environmental adaptability, microwave radar technology is widely used in various fields such as UAV ranging, automotive collision avoidance and autonomous driving radar, and vital sign detection.
