TI Single chip millimeter wave radar 1642 Code day reading （〇）—— general programme

We have entered a recent chapter from today ——3D Handle

Millimeter wave radar signal processing 3 Dimensions ：

• The first dimension ： distance
• The second dimension ： Doppler
• The third dimension ： angle

The second dimension knows the speed of the target , The first dimension and the third dimension determine the location of the target

3D The process is as follows ：

3D The processing flow is shown in the figure above , Roughly divided into EDMA Count ——>2D-DFT——> Doppler phase shift compensation ——>3D-FFT——> Find the modulus ——>XY Coordinate estimation
