&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The &amp;#039;&amp;#039;&amp;#039;Back Scattering Alignment&amp;#039;&amp;#039;&amp;#039; (BSA) is a coordinate system used in coherent electromagnetic scattering. The coordinate system is defined from the viewpoint of the wave source, before and after scattering. The BSA is most commonly used in [[radar]], specifically when working with a [[Sinclair Matrix]] because the radar detector and source are physically coaligned. BSA gives rise to  [[Eigenvalue, eigenvector, and eigenspace|conjugate eigenvalue equations]]. The alternative coordinate system in electromagnetic scattering is the [[Forward Scattering Alignment]] (FSA) which is primarily used in [[optics]]. Both coordinate systems contain essentially the same information and meaning, and thus a scattering matrix can be transformed from one to the other by use of the matrix,&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; S_{FSA} = \begin{bmatrix} 1 &amp;amp; 0 \\ 0 &amp;amp; -1 \end{bmatrix} S_{BSA}&amp;lt;/math&amp;gt;&lt;br /&gt;
