Аннотация: Рассмотрены вопросы пространственной фильтрации помех при использовании адаптивного компенсатора помех (АКП) в приемных каналах средств спутниковой навигации. Продемонстрировано влияние адаптивной коррекции частотных характеристик приемных каналов на качество подавления помех. At present, the space-time signal processing becomes onПоказать полностьюe of the main sections of the classical theory. The history of its development is more than 40 years. The bibliography on this subject is very extensive and includes a large number of reviews, scientific and applied articles, dissertations, monographs, patent materials. A significant part of the references to these sources can be found in the monographs R. Monzingo, B. Widrow. The navigation equipment of consumers of global navigation satellite systems (GNSS) should remain operable under the influence of various types of interference. Due to the low power of the useful navigation signal at the input of the receiving antenna system, the performance of the receivers becomes vulnerable in the presence of powerful intentional radio interference. Currently, to improve the quality of receivers work in such conditions, leading foreign companies such as Mitre, Navsys, Raytheon, Satimo, Electro-Radiation Inc., Mayflower Communications Company Inc., etc. are working on the creation and introduction of adaptive antenna arrays in the receivers structure). Some of the developments are carried out in the interests of the power departments of the leading countries of the world, and therefore information about the technical solutions used in them is often fragmentary.
