The paper describes a mathematical model that allows investigating fluctuation and systematic errors of angular target coordinates measurement in radar with a planar phased antenna array under action of external sources of noise radiations. Results of the mathematical simulations are demonstrated.
The analysis of spatial processing effectiveness for the two variants of smart-antenna is studied: multi-beam antenna array with beam switching and adaptive antenna array. Efficiency is measured by the output signal-to-noise ratio. The boundary values of efficiency for arbitrary noise conditions are set. The recommendations for practical application are formulated.
The paper examines the solution of scientific problem on determining the information reliability of digital channel of troposphere communication with an adaptive antenna, when signals at the output of the adaptive antenna and adaptive receiver are controlled simultaneously and compared with the fixation of the conditions of existence of informational redundancy of the channel, that automatically specifies...
Development of the theory and technology of the small element antenna arrays is one of the research areas of the Department of Technical Electromagnetics and Radio communication Systems since 2006. The research is focused on the improvement of the mobile communication systems. Curvilinear antenna arrays are proposed that comprise antenna elements with controllable polarization of radiation, which...
