The advantage of radar technology is the detection of movement, through the Doppler effect of the target echo to observe and interpret the movement state of the target, such as the movement direction and velocity; when using multi-channel sensor, the movement of the target can be observed from different perspectives. By collecting the motion state of the target from different perspectives, and analyzing the instantaneous information and historical information, the complex motion can be distinguished.

The technology of radar motion recognition can be applied in different scenes. For example, in sports, we can use this technology to detect the state and trajectory of human and ball games. In the home environment, can also do human fall detection, for the prevention of elderly falls. At present, our technology has been able to process radar data to realize the interpretation of human motion state and trajectory.

Multi sensor fusion

In the aspect of radar sensor fusion, we have achieved more reliable judgement by simultaneous interpreting the advantages and characteristics of different sensors. Many researchers have begun to combine radar and video sensing to achieve more reliable functions such as obstacle avoidance. In the future, we will see more and more applications between radar sensing and artificial intelligence.
