Abstract

In the article there are presented the mathematical and structural descriptions of the basic model of the optical correlator (BMOC), of the correlator using the matrixes of the lasers and filters (CMLF). In order to decrease the processing time in the correlators it is proposed to use the concept of the distribution of the operations of the targets detection and localization and to realize there in the different channels. At the stage of the targets detection it was proposed to use the filters generating the codified correlation functions consisting of a binary optical code which is analyzing in parallel with a high speed. There were elaborated new kinds of the correlators - with distributed targets detection and localization. There were given the analyses of the time expenditures and reliability in the different kinds of the correlators.
