mmWave Radar Sensor Guide
mmWave Radar Principle
Millimeter Wave (mmWave) radar uses Frequency Modulated Continuous Wave (FMCW) radar techniques to detect objects and their velocity, range, and angle. The FMCW radar continuously transmits a frequency-modulated signal and receives the reflected signals from objects. By analyzing the difference between the transmitted and received frequencies, the radar can determine the distance (range) and relative speed (velocity) of objects. This principle allows mmWave radar to detect fine movements, provide high accuracy, and function effectively in various environmental conditions such as rain, fog, or dust.
Different types of mmWave Radar Sensors
Millimeter-wave (mmWave) radar sensors are capable of detecting objects, measuring their distance, speed, and angle, and can penetrate various materials such as plastic, clothing, and drywall, making them suitable for a wide range of applications. In Seeed, We have leveraged the power of mmWave to come up with various sensors that can perform a variety of actions, such as fall detection and sleep breathing monitoring.
Our range of mmWave Radar Sensors are shown below, each with different features and functions.
