I was asked to calculate the radial velocity $v_r$ with MATLAB of the radar system as shown below:
We know that the radar is at [0, 0], the target is at [50, 35] and its velocity vector ($v$) is [-6, 2]m/s.
I don't know how to do it in MATLAB without knowing the angle of $v_r$ and $v$. Please give me some suggestions. Thanks so much!
