摘要/Abstract：
Introducing gesture detection scheme into ultrasonic-based gesture recognition system can reduce power consumption effectively without performing high complexity recognition operators when there is gesture.On the other hand,it can also divide the effective time segment to improve the accuracy of gesture recognition.To enhance the performance of gesture recognition system,a gesture detection scheme is proposed and the function is implemented in hardware.It adopts dual detection of moving and static targets detection and clutter map technology to provide the conditions for gesture recognition system to switch between detection mode of low power consumption and the recognition mode of high precision operation,implementing the tracking and filtering of environmental static clutter.At the same time,it solves the missed alarm caused by consecutive gestures in traditional simple moving target detection.The missed alarm rate of switching from detection mode to recognition mode in the proposed scheme is 0.The false alarm rate of switching from recognition mode to detection mode is 2%.The response time for mode switching is 733.47 ns.
