Radar

Apparently WATonomous uses this. We have a ARS430.

Radar uses radio waves. Not sound waves because those are too slow (that’s Ultrasonic Sensor? And get affected.

Radar is really good at estimating velocity since it uses the Doppler Effect.

Do their own filtering Continental are the people who provide them with radar hardware,

Take a bunch of points and convert them in bbox, we use grid-based db-scan, https://en.wikipedia.org/wiki/DBSCAN

• (NOT USED) Kalman Filter because it is a bit too difficult to implement
• DBSCAN but you need to tune that, since it uses a constant distance.
• RANSAC to do velocity estimation
  • Calculate total error, find two points that generate the least amount of error

Radars generally send data over CAN, while LiDARs generally send data over Ethernet.
