Infrared or ultrasonic technology is commonly used in human sensing applications, but it has inherent disadvantages, including low sensing accuracy and vulnerability to environmental interference. Radar is a more accurate solution.
Edge intelligence and connectivity
Radar sensors enable edge intelligence in two ways. First, Radar’s unique dataset of range, velocity, angle and its ability to reflect off different targets, enables a sensor to detect particular features of different objects in view. For example, velocity data allows the sensor to see the micro-Doppler – the modulation effect from small motions – which contains particular traits of a target, like the spinning spokes of a bicycle wheel, the swaying arms of a walking person, or the scurrying legs of an animal.
False detection reduction
Second, Radar sensors enable edge intelligence through on-chip processing. Our sensors contains a microcontroller and digital signal processor (DSP) that are capable of performing low-level radar processing, including feature detection and target object classification.
