Tytuł:: Improvement of the Microwave Imaging System by Deconvolution of the Antenna Pulse Response
Autorzy:: Bury, M.
Yashchyshyn, Y.
Modelski, J.
Powiązania:: https://bibliotekanauki.pl/articles/226958.pdf
Data publikacji:: 2010
Wydawca:: Polska Akademia Nauk. Czytelnia Czasopism PAN
Tematy:: microwave imaging
antenna pulse response
deconvolution
Opis:: In the paper a microwave imaging system and its algorithm of image reconstruction from the raw measurement data were briefly introduced. Authors observed that pulse responses of the antennas used in the system have similar duration to the measurement pulse and therefore also contribute to the limits of system resolution. Paper presents a simple method that improves the system performance by additional deconvolution of the antenna pulse responses. Method was verified experimentally.

Tytuł:: Phased array antennas in MIMO receiver
Autorzy:: Kozłowski, S.
Yashchyshyn, Y.
Modelski, J.
Powiązania:: https://bibliotekanauki.pl/articles/307622.pdf
Data publikacji:: 2007
Wydawca:: Instytut Łączności - Państwowy Instytut Badawczy
Tematy:: MIMO system
phased arrays antennas
Opis:: In this paper, a computer simulation of a MIMO system comprising phased array antennas (PAA) in all receiving branches is presented. In order to examine the system performance under relatively realistic conditions, a ray-tracing simulator was applied to generate a baseband channel impulse response matrix H. A bit error rate (BER) of two systems utilizing different detection methods: V-BLAST and simple matrix inversion was examined in order to determine phased array antennas applicability. Results of an attempt to determine relationship between BER and properties of particular matrix H realization are also provided.

Tematy:: textiles
shielding effectiveness
free-space transmission technique
time-domain gating
Opis:: The results of shielding effectiveness (SE) measurements of textile materials containing metal by the free-space transmission technique (FSTT) in the 1-26.5 GHz frequency range are presented in the paper. It is shown that experimental data processing using time-domain gating (TDG) makes it possible to effectively remove diffracted and reflected components from the desired signal. The comparison with the results obtained by other techniques, namely modified FSTT with TDG and coaxial line probe technique (ASTM D4935-99) is given. The comparison shows that the proposed technique gives more reasonable results while the measurement set-up is simpler in realization.

wireless system
Opis:: The aim of the paper is to present the concept of the integrated system dedicated for communication and remote operation of the unmanned aerial vehicle (UAV). In the paper the concept and realization of this kind of wireless communications system is presented. The system consists of two integrated solutions – unidirectional broadcast transmission of video, audio and data from UAV to the operators within the mobile command centre and two‐way communication with the telemetry and control subsystem. The systems are integrated within the single chassis and placed on the UAV to ensure proper operation of the flying robot. The specific elements of the system are presented as well as main requirements and connected with them development methods are also discussed in the paper.
