Example Embodiment
[0031] Examples:
[0032] The flow of the gesture recognition algorithm based on MIMO millimeter wave radar in this embodiment is as follows: figure 1 As shown, it includes:
[0033] 1. The millimeter wave radar transmits electromagnetic wave signals in the space to be measured, and the millimeter wave radar receives the signals reflected in the space to be measured.
[0034] 2. After ADC sampling the signal reflected from the space to be measured, perform the following operations:
[0035] 21) Perform Fourier transform on the collected signal, perform antenna signal compensation, and form a data cube;
[0036] 22) Generate azimuth direction vector according to MIMO antenna array;
[0037] 23) Use distance and azimuth virtual antenna array data combined with direction vectors to perform AOA beamforming;
[0038] 24) Perform CFAR detection on the heatMap after beam formation to obtain the distance and azimuth angle of the target point cloud;
[0039] 3. For the obtained target point cloud,...
