In this thesis work, two microstrip patch antenna arrays are designed for the traffic radar applications. Both of them operate at the 24.125 GHz with 250 MHz bandwidth. Two different series feed networks are used, namely shunt connected series feed network and in line coupled series feed network. The one with shunt connected series feed network is manufactured and measured to make comparisons with the simulation results. It is observed that simulation and measurement results are very similar. 7 degree beamwidth is achieved in both azimuth and elevation planes as well as less than -14 dB side lobe levels in the radiation patterns. In the second design, 30 degree and 12 degree beamwidths are achieved for azimuth and elevation planes, respectively. While the side lobe level of the azimuth plane is smaller than -15 dB; in the elevation plane, the side lobe level could only be minimized down to -13 dB due to the existence of delay sections.

Evaluation of multi target tracking algorithms in the presence of clutter
Güner, Onur; Kuzuoğlu, Mustafa; Department of Electrical and Electronics Engineering (2005)
This thesis describes the theoretical bases, implementation and testing of a multi target tracking approach in radar applications. The main concern in this thesis is the evaluation of the performance of tracking algorithms in the presence of false alarms due to clutter. Multi target tracking algorithms are composed of three main parts: track initiation, data association and estimation. Two methods are proposed for track initiation in this work. First one is the track score function followed by a threshold c...

Coaxial-to-microstrip launcher and microstrip patch array antenna are designed to work at center frequency of 36.85 GHz with a bandwidth higher than 300 MHz. The antenna array design also includes the feeding network distributing the power to each antenna element. The design parameters are defined on this report and optimized by using an Electromagnetic Simulation software program. In order to verify the theoretical results, microstrip patch array antenna is produced as a prototype. Measurements of antenna ...
High performance readout electronics for uncooled infrared detector arrays
Yıldırım, Ömer Özgür; Akın, Tayfun; Department of Electrical and Electronics Engineering (2006)
This thesis reports the development of high performance readout electronics for resistive microbolometer detector arrays that are used for uncooled infrared imaging. Three different readout chips are designed and fabricated by using a standard 0.6 m CMOS process. Fabricated chips include a conventional capacitive transimpedance amplifier (CTIA) type readout circuit, a novel readout circuit with dynamic resistance nonuniformity compensation capability, and a new improved version of the CTIA circuit. The fabr...
A video tracker system for traffic monitoring and analysis
Ocaklı, Mehmet; Demirekler, Mübeccel; Department of Electrical and Electronics Engineering (2007)
In this study, a video tracker system for traffic monitoring and analysis is developed. This system is able to detect and track vehicles as they move through the camera’s field of view. This provides to perform traffic analysis about the scene, which can be used to optimize traffic flows and identify potential accidents. The scene inspected in this study is assumed stationary to achieve high performance solution to the problem. This assumption provides to detect moving objects more accurately, as well as ab...
