Homework Statement
Parabolic radio telescope. Dish is fixed and across its centre a cable is suspended carrying a beam on which equipment is mounted to pick up radio waves.
Basically it's just a parabola on the cartesian plane.
How would you adjust the parabola ( focus, directrix, vertex etc ) so that the maximum intensity radio waves may be intercepted.
and any other ways such as size of dish or position of beam etc.
Thanks
Homework Equations
N/A more of a worded problem
The Attempt at a Solution
I can find information about how the size of the dish would maximize the wave intensity etc but nothing specific which is what I am looking for.
Where should the focus be on the cartesian plane? e.g How far up the y axis? How far across the x axis?
Same question for the directrix as they relate to each other ^^
Should the vertex be at the origin of the cartesian plane? Or shifted to another point? which?
Thanks
