I think the closest plotting style in gnuplot is to plot with impulses.
See for example the final plot in
   http://gnuplot.sourceforge.net/demo/poldat.html

There is a rather ugly hack that could produce plots more similar
in appearance to the example you gave.  Here is a proof of principle:

set polar
set grid polar
set border 0
set view equal xy
set size square
unset xtics
unset ytics
unset key
set rrange [.1:10]
set rtics axis scale 0.5,0 nomirror rotate by -270  offset 0, 0.7
set rtics (2,4,6,8)
set multiplot
  plot [.5:.7] 2 with filledcurves r=1
  plot [.9:1.1] 3 with filledcurves r=1
  plot [1.4:2.1] 4 with filledcurves r=.1
  plot [1.8:3.0] 3 with filledcurves r=2 lc rgb "gold"
unset multiplot
