XX7e luave itavestigated tlue jcattern fltrcttratiota in a highly developed electro-hydrodynarauic COII-vection (El,HC) by dynauaaic azaalyses of spatial Fotrrier coefficieuats of iznages. XX7e naeasured thepower spectrtrtaa and the two-tirne correlation ftrnction of spatial Fourier coefficients of itnages inthe txvo ttrrbtrlent states of EHC: the dynaraaic scattering raaode (DSIVI)l a?ad DSlVI2 states. It wasfotrnd that in the DSIVII state both tlae power spectrtruaa and tlae correlation tiuaae shoxv spatialanisotropy and have a characteristic peal< at a xvave nurnber correspondirag to the tlaickness of'the cell in the rttbbiuag directiona. Tlue peaks of tlae jcoxver spectrunu and the correlatiou'x tinaedecrease as the applied electric field is raised, and vanish entirely wlaen tlae syste?au tmndergoesthe transitiora frotaa DSIVII to DSIvI2. In the DSlN42 state, there is no anisotropy in both tlaepoxver spectrtrna and the correlation tirtue.
