There is no such predefined symbol available, I'm afraid. – egreg Feb 20 at 9:41
If there is some standard usage for this symbol can you please provide a reference -- just curious. – Peter Grill Feb 20 at 11:45
echoing @PeterGrill's comment, if there is a standard usage and a reference (in a published source), i will be happy to submit it to unicode. – barbara beeton Feb 20 at 16:48
@ Peter Grill , @ barbara beeton yes it is exists in a geometry book that i am typing now. – Hadi Safi aghdam Feb 21 at 10:24

There's no predefined symbol, as far as I know; you can get a decent emulation with picture mode. It's not really good at scriptscript size, but I don't think you'll need it at such level.

\documentclass{article}
\usepackage{pict2e}
\usepackage{amssymb}

\makeatletter
\DeclareRobustCommand{\measuredangledouble}{%
\mathord{\mathpalette\@measangdbl\relax}%
}

\newcommand{\@measangdbl}[2]{%
\sbox\z@{$\m@th#1\measuredangle$}%
\setlength\unitlength{\wd\z@}%
\ifx#1\displaystyle
\def\@mangle{50}\def\@mratio{0.96}%
\fi
\ifx#1\textstyle
\def\@mangle{50}\def\@mratio{0.96}%
\fi
\ifx#1\scriptstyle
\def\@mangle{42}\def\@mratio{0.83}%
\fi
\ifx#1\scriptscriptstyle
\def\@mangle{36}\def\@mratio{0.67}%
\fi
\begin{picture}(1,\@mratio)
\roundcap\roundjoin\linethickness{0.06\unitlength}
\polyline(0.9,\@mratio)(0.1,0.03)(0.9,0.03)
\put(0.1,0.03){\arc[-3,\@mangle]{0.4}}
\put(0.1,0.03){\arc[-3,\@mangle]{0.55}}
\end{picture}%
}
\makeatother

\begin{document}
$\measuredangle\measuredangledouble$

$\scriptstyle\measuredangle\measuredangledouble$

$\scriptscriptstyle\measuredangle\measuredangledouble$

\end{document}
