For civil and military purposes FMCW radars are widely used. The theoretical background is well-established. Nevertheless, improvement of various aspects of these radars is still required. Signal processing is one of the crucial points of the system which determines the capabilities of the radar. In this study a zero crossing detector implementation, which can be efficiently used for target detection and range calculation in short range FMCW range detector is proposed. The duration between consecutive zero-crossings are used as the data instead of the number of cycles per unit time. Experimental evaluation of its performance is also given.

Improving operational performance of antennas on complex platforms by arranging their placements Bayseferoğulları, Can; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2010) The aim of this thesis is to improve the operational performance of the communication antennas mounted on complex platforms such as aircrafts and warships by arranging placements of these antennas. Towards this aim, primarily, in order to gain insight on the influence of geometrically simple structures composing the platform on antenna performance, a quarter wavelength monopole antenna placed at the center of a finite square ground plane is studied by using uniform Geometrical Theory of Diffraction (GTD). B...
X Band TX reject waveguide bandpass filter design for satellite communication systems Çelebi, İrem; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2018) For several applications such as satellite communication, ﬁlters are required since antenna systems are operating as both receiving and transmitting. There is a possibility of leakage from transmit to the receive path in these kind of systems which needs to be isolated in order to protect equipments after ﬁlter. Low loss, high isolation and bandpass characteristics are desired for the ﬁltering, which can be validated with waveguide ﬁlters. In this study, bandpass waveguide ﬁlter design operating in X-Band f...
Target classification under multi sensor environment Atıcı, Bengü; Karasakal, Esra; Department of Industrial Engineering (2019) Radar systems have important roles in both military and civilian applications. As the capabilities increase in terms of range, sensitivity and the number of tracks to be handled, the requirement for Automatic Target Recognition (ATR) increases. ATR systems are used as decision support systems to classify the potential targets in military applications. These systems are composed of four phases, which are selection of sensors, preprocessing of radar data, feature extraction and selection, and processing of fe...
DYNAMIC MODELING AND CONTROL OF AN ELECTROMECHANICAL CONTROL ACTUATION SYSTEM Yerlikaya, Umit; Balkan, Raif Tuna (2017-10-13) Electromechanical actuators are widely used in miscellaneous applications in engineering such as aircrafts, missiles, etc. due to their momentary overdrive capability, long-term storability, and low quiescent power/low maintenance characteristics. This work focuses on electromechanical control actuation systems (CAS) that are composed of a brushless direct current motor, ball screw, and lever mechanism. In this type of CAS, nonlinearity and asymmetry occur due to the lever mechanism itself, saturation limit...
Active Control of Smart Fin Model for Aircraft Buffeting Load Alleviation Applications Chen, Yong; Ulker, Fatma Demet; Nalbantoglu, Volkan; Wickramasinghe, Viresh; Zimcik, David; Yaman, Yavuz (2009-11-01) Following the program to lest a hybrid actuation system for high-agility aircraft buffeting load alleviation oil the full-scale F/A-18 vertical fin structure, an investigation has been performed to understand the aerodynamic effects of high-speed vortical flows on the dynamic characteristics of vertical fin structures. Extensive wind-tunnel tests have been conducted on a scaled model fill integrated with piezoelectric actuators and accelerometers to measure file aft-tip vibration responses under various fre...
