Point Cloud¶
A radar point is evidence of a strong reflection at a certain range, velocity, and angle. It is not a pixel. It is a compact representation extracted from the radar cube.

doppler_bin |
Doppler bin |
angle_bin |
angle bin |
range_bin |
range bin |
Point clouds are useful because leaving is a temporal process. One frame shows a moment; a sequence shows motion. That is why the model workflow feeds point-cloud sequences into CNN + BiLSTM.
