Radar target classification method with reduced aspect dependency and improved noise performance using multiple signal classification algorithm
SEÇMEN, MUSTAFA; Sayan, Gönül (Institution of Engineering and Technology (IET), 2009-12-01)
This study introduces a novel aspect and polarisation invariant radar target classification method based on the use of multiple signal classification (MUSIC) algorithm for feature extraction. In the suggested method, for each candidate target at each designated reference aspect, feature matrices called 'MUSIC spectrum matrices (MSMs)' are constructed using the target's scattered data at different late-time intervals. An individual MSM corresponds to a map of a target's natural resonance-related power distri...
Radar cross section reduction of cylindrical cavities using ray-tracing method
Sezgin, Yusuf; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2022-5-16)
Low observability technology, which aims to make it difficult to be detected, tracked, and hit by the enemy forces is one of the most critical technologies for 5th generation fighter aircraft. Low observability in Radio Frequency (RF) band is achieved by minimizing the Radar Cross Section (RCS) of the aircraft at specific angular zones and frequencies. RCS is a quantity related to the amount of reflection of the incoming electromagnetic wave by the aircraft and it is generated by different scattering mechan...
Radar resource management techniques for multi-function phased array radars /
Çayır, Ömer; Candan, Çağatay; Department of Electrical and Electronics Engineering (2014)
Multi-function phased array radars (MFPARs) are capable of executing several tasks without any rotating antenna by jointly optimizing limited time and energy resources. The allocation of radar time resources is usually referred to as scheduling in radar resource management (RRM) literature. In this thesis, two scheduling algorithms, namely multi-type adaptive time-balance scheduler (MTATBS) and knapsack scheduler (KS), are proposed for real-time operations. A resource-aided technique called as the multi-fre...
Radar cross section analysis by shooting and bouncing rays method
Çakır, Mustafa Kağan; Tokdemir, Turgut; Department of Engineering Sciences (2015)
In this study, a MATLAB code incorporating `Shooting and Bouncing Rays (SBR) Method` is developed for calculating Radar Cross Section (RCS) of complex shapes. The code can calculate ray paths, magnetic current sheets, incident and scattered electric fields and RCS in horizontal, vertical and cross polarizations. While reflection effects are calculated by SBR algorithm, diffraction effects due to edges and corners are handled by `Equivalent Edge Currents (EEC’s)`. Wave frequency, aspect angle and number of r...
Radar emitter emulation for research and experimental purposes.
Çelebi, M. Bahadır; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2009)
The scope of this thesis is to implement radar emitter emulator in a low cost, portablehardware for operational and educational purposes. The model enables pulse train generation in real environment belonging to radar emitters for military exercises. The motivation comes from another research area which is to design effective algorithms for deinterleaving mixed pulse sequences in a suitable hardware and this thesis, covers the work done for implementing a hardware that generates mixed pulse sequences. First...
