3D model from high speed videos? Is there a way to convert or somewhat replicate RADAR data from a set of given high speed videos taken from multiple angles. 

The problem is quite ill defined but the task I have in hand is to reproduce RADAR data for a set of videos of soccer shootouts. I also have a corresponding file with the coordinates of the ball, speed of it but not quite sure how that will come into play with this.
You'd basically need to do two things:


find a 3D-model of your environment, and track the ball in that. This model needs to have knowledge of the materials involved. Since a video gives you no information on the involved object's radar reflectivity, scattering coefficients and other RF parameters, that's something that you'll have to enhance your model with – manually. 
Simulate the environment (e.g. via ray-tracing/volumetric RF FEM) as RF environment, and in that simulation emit your radar signal and observe the echo.


Honestly, I don't think this is overly viable ask "task I have", unless "I" is very much more experienced in RF simulations than I am, or "I" is a medium to large team of researchers.
