Modeling and optimization of the antenna system with focal plane array for the new generation radio telescopes with wide field of view
O. Iupikov
The model of the reflector antenna system with focal plane array, low-noise amplifier and beamformer is developed in the work. The beamformer strategy is suggested to reduce the re…

O. Iupikov
The given work is devoted to the modern developments in the field of radio astronomy instrumentation. In particular, the sensitivity of the multi-beam reflector radio telescope whi…
Analysis of receiving sensitivity of multi-beam antenna systems with a focal plane array (in Russian)
O. Iupikov
In this paper, we present a numerical electromagnetic model of a focal plane array in combination with a multi-channel receiver. Initial experimental validation results are shown t…
Effects of the Number of Active Receiver Channels on the Sensitivity of a Reflector Antenna System with a Multi-Beam Wideband Phased Array Feed
O. Iupikov
A method for accurate modeling of a reflector antenna system with a wideband phased array feed is presented and used to study the effects of the number of active antenna elements a…
