Radar System PPI polar display

I am trying to shift my current PPI slant range plot to align towards the right side of the polar plot. I am including the code which will give you a nice plot where the center of the top of the scene diagram is aligned at 90 degrees theta. I am trying to move my scene diagram towards the right of polar plot as seen in the second attached pic entitled "stuff 2".. Any suggestions? This is supposed to mimic a PPI dispaly 1.8km from a radar(or 200m) above ground. Thanking you in advance. By the way, I think my first plot is correct because my rho calculatiuons match Matlabs R points. Here is the current code.

% x = [5 5 5 5 4 4 4 4 4 3 3 3 3 3 3 0 0 0 0 0 0 1.5 5 5 5 5 5 5];

% y = [10 9 3 0 10 9 8 3 0 10 9 8 7 3 0 10 6 5 4 3 0 5 10 6 5 4 3 0];

% h = [1.8 2 2 2 2 1.8 2 2 2 2 2 1.8 2 2 2 2 2 1.8 2 2 2 1.8 2 2 1.8 2 2 2];

% phi = [-26.6 -29.1 -59.1 -90 -21.8 -24.0 -26.6 -53.1 -90 -16.7 -18.4 -20.6 -23.2 -45 -90 0 0 0 0 0 0 21.8 26.6 39.8 45 51.3 59.0 90];

% rho = [9.72 8.69 4.36 3.59 9.15 8.41 7.37 3.59 2.67 8.83 7.89 7.13 6.07 2.89 1.81 8.40 4.52 3.72 2.67 1.81 0.2 4.08 9.56 6.26 5.7 4.91 4.36 3.59];
