This paper discusses the synthesis of an algorithm for adaptive interference nulling of an 8-element phased antenna array. An adaptive beamforming system has been built on the basis of the algorithm. The paper discusses ...
Specialized software for the adaptive nulling unit of a hybrid reflector antenna
This paper considers the development of specialized software for a hybrid reflector antenna adaptive nulling unit; it conducts the calculation of a desired amplitude and phase distribution of the feed array in counter ...
Simulation modeling of functional adaptive interference nulling for multibeam hybrid reflector antenna systems
This paper considers the simulation of adaptive nulling mechanism patterns in hybrid reflector antenna systems with a 19-element feed element, in which the radiation pattern is formed as a cluster. Incidents of broadband ...
Applying filtering for determining the angular orientation of spinning objects during interference
This article discusses the application of user navigation equipment of satellite radionavigation systems (GLONASS/GPS) for measuring the inclination of the aerial axis of rotation. The authors have demonstrated that the ...
An adaptive algorithm for interference suppression in phased antenna arrays
This paper describes an algorithm designed for adapting a phased antenna array to an interference environment. Based on this algorithm, the authors have proposed a design of an adaptive beamformer.
Electromagnetic compatibility of ground system of near navigation, based on the use of GNSS and pseudolites
Article describes the results of modeling the allowable power pseudolites in the ground system of near navigation, working together with GLONASS. Was justified pulsed operation of pseudolites and using weighting windows ...
Pseudolite systems for close-range navigation: The problem of synchronization
This paper discusses the implementation of an electronic pseudolite close-range navigation system provided that one of the pseudolites is located at a certain altitude. The authors have developed principles for building a ...
