The polarimetric response of radar targets can be decomposed into a set of so-called Huynen-Euler parameters which allow to analyze the physical scattering mechanism occuring at the target. Required for this technique is a coneigenvalue decomposition, whose characteristics are not yet fully unterstood. Due to this there are conflicting opinions regarding the question if one of the Huynen-Euler parameters, the skip angle, can be extracted from the coneigenvalues. This paper resolves this conflict by discussing the mathematics of coneigenvalues and by giving a physical interpretation to the coneigenvalue decomposition.
