ENSURING IMMUNITY OF DATA TRANSMISSION OVER RADAR COMMUNICATION CHANNELS

Abstract

The article explores the ways o f forming an adaptive coding algorithm 8/16 bits per baud for control or remote control signals with specified quality criteria in a physically non-expandable data transmission channel. The combination o f bearing and information exchange systems in one radar station faces difficulties in forming a transmitted message. It is necessary to use noise-proof methods o f convolutional coding in order to detect transmitted message bits in linear frequency modulation band o f the probing and reflected signals. The formation o f a broadband signal using a fractional Fourier transform provides the formation o f message protocols by multiplexing with orthogonal frequency division. The proposed coding method implements error-correcting coding in the ratio o f 8 or 16 bits per baud. The use o f radio communication in the navigation radar band makes it possible to implement the concept o f a combined intelligent transport system
