PolarPlot Axes Shape Change

Hello everyone! I am trying to replicate the graph (2) generated regarding directivity of sound. I have managed to create a polar plot (1) but am not sure how I can change the shape of the axes so that the range of radii shown as a grid does not start from the centre of the circle. Just wanted to minimise the space taken by the plot if I can remove part of the centre of the plot. From the images, I want 1 to look like 2.

% data:
th = deg2rad(50:10:140);
r1 = 70+20*rand(size(th));
r2 = 50+20*rand(size(th));

% polaraxes setup:
f = figure('Color',0.94*[1 1 1]);
ax = polaraxes();
polarscatter(ax,0,0,25000,f.Color,'filled','Clipping','off');
ax.ThetaLim = [0 180];
ax.NextPlot = 'add';

% plot:
h1 = polarplot(ax,th,r1,'-r^','MarkerFaceColor','r');
h2 = polarplot(ax,th,r2,'-bv','MarkerFaceColor','b');
legend([h1 h2],{'Baseline','LE3S'},'Location','South')
