Radar systems and communication systems play a vital role in military and commercial usage of information transmission. The concept of integration these systems in a single platform with joint waveform is called as RADCOM (Radar and Communication). MIMO structures are promising systems to provide time-frequency and space usage approach with having multiple transmit and multiple receive antennas integrated in single platform. MIMO radar transmits multiple probing signals via transmit antennas and receiving antennas are used for receiving echos from these transmitted signals. In this thesis, co-located MIMO RADCOM systems that use signal sharing method with OFDM modulation are studied. Channels are spatially correlated Rician fading, i.e. channel model is composed of a line-of-sight path. Channel covariance matrix (CCM) is constructed parametrically depended on channel correlation information (angle of arrival and angular spreads). Received signal from channel is used to provide target map. Radar data cube, ie. target map, is constructed by range, angle and doppler information.

Design of miniaturized ku band narrowband cavity filter Sevinç, Yusuf; Demir, Şimşek; Department of Electrical and Electronics Engineering (2018) Frequency multiplexer structures are of a crucial role as an essential part of huge variety of communication systems including, satellite-communication systems, wireless communication systems and radio transmission. They are indispensable multiple port components that are used for combination and separation of specific signals or frequency bandwidths selectively from a single signal or frequency bandwidth in multiport communication system. The main blocks that form a multiplexer are a set of filters, named ...
Interoperability Profiles for Disaster Management and Maritime Surveillance Gencturk, Mert; Duro, Refiz; Kabak, Yildiray; Bozic, Bojan; Kahveci, Kubilay; Yilmaz, Burcu (2015-11-26) Nowadays, many different Command and Control (C2) Systems and Sensor order to manage disasters effectively and achieve powerful surveillance, it is essential for C2 and Sensor Systems to cooperate and exchange timely available, reliable and intelligible information. Although globally accepted standards are used commonly in C2 and Sensor domains, there is no single specification of using these standards together for cooperation of disparate systems, which creates a crucial interoperability challenge. To addr...

True-time delay structures for microwave beamforming networks in S-band phased arrays Temir, Kaan; Demir, Şimşek; Department of Electrical and Electronics Engineering (2013) True time delay networks are one of the most critical structures of wideband phased-array antenna systems which are frequently used in self-protection and electronic warfare applications. In order to direct the main beam of a wideband phased-array antenna to the desired direction; phase values, which are linearly dependent to frequency, are essential. Due to the phase characteristics of the true-time delay networks, beam squint problems for broadband phased array systems are minimized. In this thesis, diffe...
Cyber Warfare Integration to Conventional Combat Modeling: A Bayesian Framework Sengul, Zafer; Acartürk, Cengiz (2021-01-01) © 2021 IEEE.Malware propagation is capable of introducing adverse effects in military operations since today's high-tech military weapons and command, control, and communication systems are essentially interconnected ICT systems. Conventional warfare models have been recently upgraded to include cyber warfare elements to reflect the potential influence of cyber-attacks. In the present study, we propose and evaluate a framework for modeling the integrated effect of the spread of malware through computer netw...
