5.3 Data Post-Processing

After acquiring the raw ADC data, users can refer to the MATLAB code in MMWAVE_L_SDK_05_05_04_02\tools\ADC_parser for data post-processing. After performing 2DFFT calculation and processing on the data, the Range-Doppler heatmap is obtained. As shown in Figure 5-3, they are the heatmaps before (left) and after (right) enabling the look-up table frequency hopping. After enabling frequency hopping, it can be seen in the figure that the stationary target in the middle of the image generates an offset in the Doppler dimension. This characteristic tilt verifies that we have successfully enabled frequency hopping on the AWRL1432 chip.
