Забезпечення завадозахищеності приймачів сигналів GNSS шляхом використання алгоритмів просторової фільтрації

The required level of radio-electronic protection of satellite radio navigation signal receivers (SRNS) providing ground-based weapons and military platforms is being evaluated, taking into account possible radio-electronic suppression by the enemy. An adaptive algorithm for spatial filtering of the SNNS signals under the influence of specially organized interference by the enemy, based on the recurrent method of forming the estimation of the inverse correlation matrix, is considered. On the basis of this algorithm a model of functioning of the noise immunity receiver of the SNNS signal under the conditions of active interference is created. Using the created model, the efficiency of the operation of the noise immunity receiver of the SNNS in the conditions of radio-electronic suppression is evaluated.
