This study which was conducted as a Master's thesis, is a radar system working at X band. In this system, a 0.8 Watts continuous electromagnetic wave which is modulated with a frequency ramp of 30 MHz bandwidth is generated and radiated through transmit antenna. The scattered signal from the hydrometeors is multiplied with the transmitted one and the beat signal is obtained. By this deramping process the range information of the target is converted into frequency domain. Data is processed in Matlab after passing through analog to digital converters. The range and velocity information is obtained with signal processing algorithms in fast and slow time. Some special techniques such as clipping, windowing, coherent data integration, and slow time signal processing are performed to the captured beat signal. Verification of the system is performed by buildings and cars whose range and velocities are known. The range of cloud and the speed of wind are estimated by processing the return signal in fast and slow time.

Polarimetric FMCW Weather Radar Coskun, Salih; Yılmaz, Ali Özgür; Koç, Seyit Sencer; Celik, Mert (2015-05-19) This study which was conducted as a Master's thesis, is a radar system working at X band. In this system, a 2 Watt continuous electromagnetic wave which is modulated with frequency ramp of 30 MHz bandwidth is generated and radiated through TX antenna. The scattered signal from the hydrometeors is multiplied with the transmitted one and beat signal is obtained. By this deramping process the range information of the target is converted into frequency domain. Data is processed in Matlab after passing through a...
Doppler radar target recognition by neural networks Erdoğan, Alpay; Halıcı, Uğur; Department of Electrical and Electronics Engineering (2002) In this thesis, automatic recognition of Doppler radar targets is studied. The Doppler signal characteristics enabling target classification are discovered. The main intention is to identify the factors affecting target characteristics such as target speed, target aspect angle, target range and radar system effects. Proper preprocessing and normalization techniques are explored and applied to obtain invariant features against those factors. Extracted features are analyzed for class separability through clus...
Doppler radar data processing and classification Aygar, Alper; Halıcı, Uğur; Department of Electrical and Electronics Engineering (2008) In this thesis, improving the performance of the automatic recognition of the Doppler radar targets is studied. The radar used in this study is a ground-surveillance doppler radar. Target types are car, truck, bus, tank, helicopter, moving man and running man. The input of this thesis is the output of the real doppler radar signals which are normalized and preprocessed (TRP vectors: Target Recognition Pattern vectors) in the doctorate thesis by Erdogan (2002). TRP vectors are normalized and homogenized dopp...
AN INTERFEROMETRIC TECHNIQUE FOR MEASURING MICRON LEVEL CLEARANCES FILLED WITH A LUBRICANT Yildirim, Murat; Dursunkaya, Zafer; Okutucu Özyurt, Hanife Tuba (2010-10-20) The aim of this study is to develop an interferometric technique to measure micron level clearances occurring in small piston-cylinder arrangements; such as hermetically sealed compressors. A Cartesian model of the piston cylinder arrangement is manufactured and lateral and vertical motions are generated via a step motor, and micrometers, respectively, to simulate the piston motion and the change of clearance during the motion. Experiments are conducted in air and a lubricant. Measurements show the importan...
Frequency Modulated Continuous Wave Radar for Range Detection Kaya, Tevfik; Sahin, Enes Burak; Nesimoglu, Tayfun (2018-11-02) In this paper, a Frequency Modulated Continuous Wave Radar is built using radio frequency techniques. Radar can measure the nearest object's range from 2 to 30 meters with 1-meter range resolution. The design process was carried out by using computer-aided design techniques, and mathematical tools. The hardware prototype was built and measurements were carried out confirming successful operation of the range detection radar.
