Materials having radar absorbing property show critical importance for space vehicles in defense industry. Among all of the radar absorption mechanisms, use of frequency selective surface has become prominent. In this thesis, composite material having frequency selective surface was developed, manufactured and characterized. Designing of frequency selective surface operating in 8.2 – 12.4 GHz frequency range was conducted by means of finite element analysis method. In addition to radar absorbing performance, it was aimed to attain a material that can be used in structural parts. Therefore, frequency selective surface design procedure was carried out considering processability and mechanical properties of composite material. Radar absorbing performance of developed composite material was illustrated by using NRL Arch free space method. Furthermore, mechanical, thermal and physical characterization tests were applied.

Coordinated guidance for multiple UAVs Cakici, Ferit; Ergezer, Halit; Irmak, Ufuk; Leblebicioğlu, Mehmet Kemal (2016-05-01) This paper addresses the path planning problem of multiple unmanned aerial vehicles (UAVs). The paths are planned to maximize collected amount of information from desired regions (DRs), while avoiding forbidden regions (FRs) and reaching the destination. This study focuses on maximizing collected information instead of minimizing total mission time, as in previous studies. The problem is solved by a genetic algorithm (GA) with the proposal of novel evolutionary operators. The initial populations are generat...
Shock Response of an Antenna Structure Considering Geometric Nonlinearity Ozcelik, Yunus Emre; Ciğeroğlu, Ender; Çalışkan, Mehmet (2016-01-28) Antenna structures used in electronic warfare, radar, naval, satellite, spacecraft systems encounter mechanical shock from various sources such as near miss under water explosion, pyrotechnic and ballistic shocks. Since most of the antenna structure has larger dimension in longitudinal direction and experience high frequency, high amplitude shock energy, geometric nonlinearity become crucial to predict dynamic behavior in real life. In this study, the antenna structure is modeled by Euler-Bernoulli beam the...
Vision-Based Detection and Distance Estimation of Micro Unmanned Aerial Vehicles Gökçe, Fatih; Üçoluk, Göktürk; Şahin, Erol; Kalkan, Sinan (MDPI, ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND, 2015-9) Detection and distance estimation of micro unmanned aerial vehicles (mUAVs) is crucial for (i) the detection of intruder mUAVs in protected environments; (ii) sense and avoid purposes on mUAVs or on other aerial vehicles and (iii) multi-mUAV control scenarios, such as environmental monitoring, surveillance and exploration. In this article, we evaluate vision algorithms as alternatives for detection and distance estimation of mUAVs, since other sensing modalities entail certain limitations on the environment...
Experimental investigation of morphing wing aerodynamics by force measurements and particle image velocimetry Özçakmak, Özge Sinem; Özgen, Serkan; Department of Aerospace Engineering (2015) Recently, new developments in on manufacturing technologies, aircraft materials, sensors, actuators, and other mechanisms raised the interest in morphing wings. Instead of conventional wings, which are optimized only for one flight condition, morphing wings can adapt themselves for different missions, mission segments and associated flight conditions. The focus of this thesis is the experimental analysis of a morphing wing, the planform and airfoil shapes that were made available from a separate numerical s...
Real-Time Attitude Independent Calibration of Spinning Spacecraft Magnetometers Using Quasi-Measurements Cetin, Mustafa Efe; Söken, Halil Ersin; Sakai, Shin-ichiro (2022-11-01) Magnetometers are essential sensors for attitude estimation in small spacecraft due to their robust, inexpensive, and lightweight characteristics. However, the raw measurements contain sensor errors. These errors degrade the attitude estimation accuracy. This study proposes a complete real-time attitude-independent magnetometer calibration algorithm for spinning spacecraft. The recursive algorithm aims to estimate the full error state, bias, scale factor, and non-orthogonality corrections in real-time and w...
