Modern phased array radars require large numbers of electronically controlled phase shifters to steer their beams to the desired direction. The amount of beam steering error depends on the phase resolution of the phase shifters as well as the performance of other parts of the antenna system. The size of the phase shifter in such systems is most of the time needed to be small, which necessitates the MMIC implementation. In the context of this thesis, an X band 7 bit MMIC phase shifter of 2.8125 degree phase resolution, including its layout, is designed using the design kit of OMMIC® Foundry. All bits of the phase shifter are designed to have low return loss so as to minimize the performance egradation due to loading effects upon cascading. Also some structures studied using the design kit of WIN® Foundry are presented. Both designs were performed using ADS®. For the optimum cascading of 7 bits, a MATLAB code was written and used.

Development and comparison of autopilot and guidance algorithms for missiles Evcimen, Çağdaş; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2007) In order to have an interception with a target, a missile should be guided with a successful guidance algorithm accompanied with a suitable autopilot structure. In this study, different autopilot and guidance designs for a canard-controlled missile are developed. As a first step, nonlinear missile mathematical model is derived by using the equations of motion with aerodynamic coefficients found by Missile DATCOM program. Autopilot design starts by the linearization of the nonlinear missile model around equi...
Modeling, stability analysis and control system design of a small-sized tiltrotor uav Çakıcı, Ferit; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2009) Unmanned Aerial Vehicles (UAVs) are remotely piloted or self-piloted aircrafts that can carry cameras, sensors, communications equipment or other payloads. Tiltrotor UAVs provide a unique platform that fulfills the needs for ever-changing mission requirements by combining the desired features; hovering like a helicopter and reaching high forward speeds like an airplane. In this work, the conceptual design and aerodynamical model of a realizable small-sized Tiltrotor UAV is constructed, the linearized state-...
S-band hybrid 4 bit phase shifter using cots components Erkek, Eser; Demir, Şimşek; Department of Electrical and Electronics Engineering (2009) Microwave and millimeter-wave phase shifters are one of the most important structures of the antenna series that are used in communication and radar applications. They are used to form the main beam of the electronically scanned phase array antennas and generate the appropriate phase values for the antenna elements design while providing electronic beam steering. In this thesis, S-band hybrid 4 bit phase shifter of 22.5º phase resolution is designed, simulated, fabricated and measured. Bits are separately d...
Power stage design and implementation of a deploymentmechanism driver for space applications Özdemir, Başak Gonca; Hızal, Mirzahan; Department of Electrical and Electronics Engineering (2012) With the developments in space technology, the capabilities of spacecrafts have been increased considerably which in turn have entailed the development of more efficient spacecrafts in terms of cost, mass, size and power. One way to achieve such a development is the replacement of body mounted appendages with the deployable ones, which greatly reduces the size, mass and cost of the spacecraft especially when large appendages are considered. In order to obtain these deployable structures, deployment mechanis...
Design of a slotted waveguide array antenna and its feed system Top, Can Barış; Hızal, Altunkan; Department of Electrical and Electronics Engineering (2006) Slotted waveguide array (SWGA) antennas find application in systems which require planarity, low profile, high power handling capabilities such as radars. In this thesis, a planar, low sidelobe, phased array antenna, capable of electronically beam scanning in E-plane is designed, manufactured and measured. In the design, slot characterization is done with HFSS and by measurements, and mutual coupling between slots are calculated analytically. A MATLAB code is developed for the synthesis of the SWGA antenna....
