Frekans Modülasyonlu Sürekli Dalga (FMSD) Ölçüm Sistemlerinde Faz Gürültü Etkisinin Telafisi

Abstract

Bu makalede, tüm tasarım parametreleri dikkate alınarak, Frekans Modülasyonlu Sürekli Dalga ölçüm sistemlerinde (FMSD) kullanılan faz gürültüsü telafi algoritmalarının analizi sunulmuştur. Bu sayede radyo frekansından optik frekanslara kadar FMSD-tabanlı sistemler için genel ve gerçekçi bir model oluşturulmuştur. Önerilen faz gürültüsü telafi algoritmasının geçerliliği benzetimler aracılığı ile doğrulanmıştır. Benzetim sonuçları makalede sunulan matematiksel modeller ile uyum içerisindedir. Bu çalışma, doğrusal olmayan frekans modülasyonun ortaya çıkardığı pahalı ve karmaşık donanımsal gereksinimlerin üstesinden gelinebilmesini sağlayarak, birden fazla teknolojik alanda (örn. SAR radarlar, fiber optik sensörler) etki yaratabilir

Phase Noise Compensation in Frequency Modulated Continuous Wave (FMCW) Measurement Systems

Abstract

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.
