    Toward Cost-Effective and Lightweight Doppler Radars: Papercraft-Based Components and Comparisons With Aluminum and 3-D Printed Alternatives
    (Institute of Electrical and Electronics Engineers Inc., 2024) Karatay,A.; Atac,E.; Yaman,F.; 01. Izmir Institute of Technology
    Doppler radar systems have an essential role in various applications, including aviation, weather forecasting, and military surveillance. However, their high fabrication costs and heavy weight may limit their utilization in rapid prototyping, small-scale applications, and seamless transportation. To address these challenges, a novel papercraft-based approach for producing the entire Doppler radar system's horn antenna, hybrid tee, and short termination components in the X-band was investigated with details in this study, alongside conventional aluminum and 3-D printing methods. This article presents the first attempt to develop a Doppler radar using papercraft-based manufacturing. The papercraft-based approach is cost-effective, lightweight, flexible, and readily available, offering a promising route for improving and fabricating Doppler radar systems that are both affordable and accessible, particularly in resource-limited settings. The experimental results show that the papercraft-based components can perform comparably to conventional aluminum-based and 3-D-printed components, making it an innovative and cost-effective solution for fabricating Doppler radar systems. © 2023 IEEE.

    Phase Noise Compensation in Frequency Modulated Continuous Wave (fmcw) Measurement Systems
    (Gazi Üniversitesi, 2018) Vardarlı, Eren; Yüksel Aldoğan, Kıvılcım; Yüksel Aldoğan, Kıvılcım; 03.05. Department of Electrical and Electronics Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    We present the analysis of the phase noise compensation algorithms used in Frequency Modulated Continuous Wave measurement systems taking into account all the design parameters. This allows obtaining a generic yet realistic framework for the FMCW-based systems ranging from RF to optical frequencies. The efficiency of the proposed phase-noise compensation algorithm has been verified by the way of simulations. The simulation results show a good agreement with the mathematical foundations discussed in the paper. This work could have a technological implication in many fields (e.g. SAR radar, optical fiber sensor interrogation) in such a way that the stringent and expensive hardware requirements due to nonlinear frequency modulation effects can be overcome a posteriori by the phase noise compensation algorithm demonstrated in this article.
