Hizal, Altunkan
Demir, Şimşek
An FMCW radar waveform design based on stretch procesing is described. Transmit (TX) and Receive (RX) functions are separated in time. A single antenna with no isolation problems can be used. A rigorous analysis of coherent processing is presented. Advantages and disadvantages are discussed. Compared to Pulsed Doppler Radar (PDR) this waveform has significant LPI properties. A generic design example is also given.

ATTITUDE CONTROL OF MULTIPLE RIGID BODY SPACECRAFT WITH FLEXIBLE HINGE JOINTS
Akbulut, Burak; Özgören, Mustafa Kemal; Tekinalp, Ozan (2010-02-18)
Control algorithm is developed for a satellite with flexible appendages to achieve a good pointing performance. Detailed modeling activity was carried out that consists of sensor and actuator models, disturbances and system dynamics. Common hardware found in the spacecraft such as reaction wheels, gyroscopes, star trackers etc. were included in the model. Furthermore, the Newton-Euler method is employed for the derivation of multi-body equations of motion. Proper metrics such as accuracy, jitter and stabili...
Linear prediction for single snapshot multiple target doppler estimation under possibly moving radar clutter
Öztan, Baha Baran; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2008)
We have devised a processor for pulsed Doppler radars for multi-target detection in same folded range under land and moving clutter. To this end, we have investigated the estimation of parameters, i.e., frequencies, amplitudes, and phases, of complex exponentials that model target echoes under radar clutter characterized by antenna scanning modulation with observation limited to single snapshot, i.e., one burst. The Maximum Likelihood method of estimation is presented together with the bounds on estimates, ...
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.
Measurement of chi(c1) and chi(c2) production with root s=7 TeV pp collisions at ATLAS
Aad, G.; et. al. (2014-07-01)
The prompt and non-prompt production cross-sections for the chi(c1) and chi(c2) charmonium states are measured in pp collisions at root s = 7TeV with the ATLAS detector at the LHC using 4.5 fb(-1) of integrated luminosity. The chi(c) states are reconstructed through the radiative decay chi c -> J/psi gamma ( with J/psi -> mu(+)mu(-)) where photons are reconstructed from gamma -> e(+)e(-) conversions. The production rate of the chi(c2) state relative to the chi(c1) state is measured for prompt and non-prompt...
Numerical and Experimental Investigation of Rotor Aerodynamics In Ground Effect with Inclined Planes
Şahbaz, Mehmet; Sezer Uzol, Nilay; Kurtuluş, Dilek Funda (null; 2019-11-02)
In this work, the ground effect phenomena for a rotary wing is investigated both numerically and experimentally. For this purpose, a test setup with scaled model helicopter rotor is established. The experimental setup give the opportunity to investigate the rotor aerodynamics both with inclined ground and without any inclination. The thrust and torque values are obtained for different rotational speeds with constant collective pitch. The effects of the inclined ground and the effects of the ground with extr...
