Optical recognition of one-dimensional signals represented on the phase plane

摘要

Abstract: Structural correlation analysis is carried out for 1D signals, represented as phase images. For LFM signals, mapped into generalized phase plane with coordinates x $EQ S, y $EQ S$DPRM@/S, sensitivity of correlation analysis to staggering of deviation frequency is invariant to impulse duration and increase with increase of carrier frequency and decrease of initial deviation. Phase representation of LFM signals essentially improves the sensitivity of coherent optical processing in comparison with binary raster representation. !5
