Radar System PPI polar display

Greetings,

Iam trying to add some concentric circles to my polar plot graph. All my code is correct and the R values on the polar plot closely resemble my rho analytical calculations. I just would like to add some more circles ranging, for example, from 0,2,4,6,8,and10,instead of what my current plot shows that just displays 0,5,10. I tried adding radii to my code with no luck. Is this posssible, or is that polar graph a Matlab default which cannot be tweaked? I attached a pic of my code and current polar plot .Thanks for your assistance in advance!!

You can set the RTick value as follows:

theta = linspace(0,2*pi);
rho = 20*sin(theta);
subplot(1,2,1);
polarplot(theta,rho);           % Polarplot from default settings
subplot(1,2,2)
polarplot(theta,rho);
ax = gca;                       % Get the axis handle of the current figure
ax.RTick = 0:2:20;              % Set the required RTick values
