CSOM

Based on https://github.com/JustGlowing/minisom. In order to classify goals by unsupervised-learning, I am using SOM (Self organizing maps neural network) to process MIMO-FMCW radar. Here is the setting of experiment and original images.

We can see the reflector is the field be circled on the left side of radar heatmap. And I am coding the complex-value SOM to make better use of the amplitude and phase data of radar.

dbf algorithm

dbf.py is a python file to achieve digital beamforming algorithm for estimation of direction of arrivals.
