Dear Matlab Community,
I would like to plot Signal strength values of a satellite, according to its elevation (radius) and its azimuth (angle) (from an earth station point of view) in a polar plot. My inputs are:
- a 91x361 matrix with elevation values,
elevation = pi/180*(0:90);
elevation_grid = elevation'*ones(1,length(azimuth));
- a 91x361 matrix with azimuth values,
azimuth = pi/180*(0:360);
azimuth_grid = ones(length(elevation),1)*azimuth;
- a 91x361 matrix with signal strength values (SNR_grid), of course this matrix contains NaN value because satellite will never have some couple of (elevation, azimuth) as coordinates.
My point is to make correspondences between the 3 matrices. If I look at element (n,p) in elevation_grid and in azimuth_grid, it gives me the corresponding signal strength in SNR_grid.
For now, I used the "surface" function. It gives me such result :
But I would like to have that in a polar plot. 0° must be North (on top of the graph) and the angle should be measured in geographic direction (not trigonometric), that means clockwise.
I thank you very much for your help.
