Ulf-Vlf-Lf Bantları için Alıcı Tasarımı ve Geliştirilmesi
(Fen Bilimleri Enstitüsü, 2019)
ULF-VLF-LF bands are the frequency range of 300 Hz to 300 kHz, where the low frequency signals with long wavelengths that are emitted from artificial or natural sources propagates. Since the signals observed in this frequency ...
GPS Verilerini Kullanarak Alıcı ve Uydu Cihaz Yanlılık Değerlerinin Kestirilmesi
(Fen Bilimleri Enstitüsü, 2019)
For radio communication systems, navigation systems and short wave implementations using radio waves, free electron content in ionosphere is important. One of the most important parameter to track the changes in ionosphere ...
İyonkürede Dalga Yayılımı Modellemesi için Işın İzleme Algoritmalarının Grafik İşlemci Birimleri ile Paralel İşlenmesi
(Fen Bilimleri Enstitüsü, 2018-04-11)
In long range short wave (SW) communications, the transmitted signal passes through the
ionosphere. Ionosphere approximately covers the area between about 80 kms and 1100 kms
above the earth’s surface and it is mostly ...
Darbant ve Genişbant Sanal İyonosonda için Sinyal İşleme Teknikleri
(Fen Bilimleri Enstitüsü, 2018-07)
One of the mostly used band for long range communication is High Frequency (HF)
band. Radio waves in the HF band range (3 − 30 MHz) are reflected from ionosphere
which is one of the layers of atmosphere. So, a communication ...
Gelecek Nesil Radyo Erişim Ağlarında Dinamik Kaynak Yönetimi
(Fen Bilimleri Enstitüsü, 2018)
In this thesis, radio resource allocation in a downlink multi-cell and multi-carrier distributed antenna system (DAS) are discussed.
In these problems, performances of non-orthogonal multiple access (NOMA), multi-connectivity ...
Sürekli Dalga Radar Sistemlerinde Özgirişim Tekniklerinin İncelenmesi
(Fen Bilimleri Enstitüsü, 2022-09-30)
In the past, FMCW radars were not preferred in the industry because they were large and bulky. With developing technology, they have expanded their usage areas due to the high resolution, low transmission power, simpler ...
Zaman Gecikmeli Sistemlerin Denetimi
(Fen Bilimleri Enstitüsü, 2022-09)
Time delay is considered to have infinitely many poles in the frequency domain by its nature and it is known that the control is harder when the delay is present in the system. The purpose of this thesis is to compare the ...
Anti-Balistik Füzelerin Ateş Kontrolü
(Fen Bilimleri Enstitüsü, 2022-09)
This thesis aims to examine the Air Defense Missiles that arise as a need against the
developing ballistic missile technology day by day and to create doctrines about the
capability of Anti Ballistic Missile Systems that ...
Hücresel Haberleşme Sistemlerinde İHA Haberleşme Kanal Modellerinin İncelenmesi
(Fen Bilimleri Enstitüsü, 2022)
There are a number of challenges involved in establishing air corridors for flight routes and integrating unmanned aerial vehicles into an automated system that will not pose a threat to the society. The primary objective ...
Kodlanmış Metamalzeme ile Radar Soğurucu Malzeme Tasarımı
(Fen Bilimleri Enstitüsü, 2023-07)
The importance of the RADAR systems that detect, identify and track an object/target is increasing day by day in military and civilian fields. One of the most important parameters of RADAR system performance is RADAR cross ...
