I’ve heard that a speed gun uses the Doppler effect to do some calculation and get the speed of a car, but can it work on multiple vehicles at the same time? How is it possible?
In: Physics
The technology makes it possible. Doppler radar or lidar can track the position of every dimension it can see from its origin, and then you just need some intelligence for entity extraction. Audio arrays can record an entire stadium, and then using phase cancelling techniques, let you hone in on a single conversation in real-time or in playback.
However, the concept of “gun” means that it is being aimed to target a single suspect, and to then produce evidence. Speed cameras or red light cams will have lane targets.
I want a video heat map audio “radar” set up for the truckers and Harleys that violate jake brake regulations at 3AM.
