Carlo,
maybe this helps:

\documentclass[11pt]{article}
\usepackage{pst-plot}

\begin{document}
\begin{pspicture}(-6,-6)(6,6)
\psaxes[axesstyle=polar,subticklinestyle=dashed,subticks=2,Dy=45](5,360)
\psplot[polarplot,algebraic,linecolor=blue,linewidth=2pt,plotpoints=1000]{0}{20}{0.2*(sin(x)+x)}
\psaxes[yAxis=false,Dx=0.1,dx=1cm,xlabelPos=top](5,5)
\psplot[polarplot,algebraic,linecolor=red,linewidth=2pt,plotpoints=1000,unit=10]{0}{20}{0.2*(cos(x)+1)}
\psplot[polarplot,algebraic,linecolor=green,linewidth=2pt,plotpoints=1000,unit=20]{0}{20}{-0.2*sin(x)}
\end{pspicture}
\end{document}
