Description

Found that the main factor limiting the effectiveness of the anti-jamming in conditions of active noise that is the phase error of the analog automatic compensator interference variable when scanning antenna interchannel delay of the wave front of interfering signals and their multipath propagation. In the context of the combined effects of noise due to the ambiguity of the main limitations of the classification sample selection to adapt the weighting coefficients of the automatic compensator. It is shown, that to be more effective in suppressing the jammer it is necessary to use a digital realization of the space-time filter with the compensation of interference in the band, consistent with the spectral width of the probe signal when upgrading radar 36D6 . In order to increase the quality of noise reduction in a multipath environment, as well as the existing variable when scanning antenna inter-channel delay of interfering signals, it is necessary to use an automatic compensator transversal filter. To improve the efficiency of the system in a combined anti-jamming interference offered several options for the formation of the classification of the sample.
