A HARDWARE-SOFTWARE SYSTEM FOR AUTOMATED DETECTION WITH IDENTIFICATION OF COVERT RADIOELECTRONIC MEAN

Abstract

Аn overview of main characteristics of modern non-linear radiolocators is presented. The main factors that negatively affect the health of operator are identified. The analysis of the effective methods of searching, detection and identification of covert radioelectronic means is carried out. It is noted that the accuracy of the radio-electronic means identification depends on the selection criteria of the classification system. It presents a fundamentally new way to recognize the type of semiconductor based on the use of a special probing AM-signal with suppressed carrier (DSB-signal). The possibility of automated identification on the basis of developed method of nonlinearity recovery is demonstrated. The results of modern and developed methods in the form of a chart of their performance are provided. The block-diagram of hardware-software system developed for detection and identification of covert radioelectronic means is designed. The term «identity portrait» is deseribed. A method for producing an identification portrait is introduced. The work presents the real current-voltage characteristics of I307G and D18 diodes and reconstructed ones performed by calculating the approximating polynomial coefficients of the third degree. Identification portraits of I307G and D18 diodes are provided.
