Paper Abstract

The outstanding role of the optical coherent Fourier processor and the instantaneous spectrum computed with is considered when performing spectral-correlation processing of the signals of the radio and optical bands. Within the framework of the performed studies, the spread functions for "real spectral devices in an ideal implementation" are established. The sampling theorem for the instantaneous spectrum is proved. These general theoretical studies are used to develop the theory of a diffraction grating spectral device of the optical range, as well as an acoustooptic (AO) radio signal analyzer, and the coordinated filter and a correlator of radio signals created on its basis.
