Infrared imagery is widely used in many applications in both civilian and military areas. In landmine detection, the goal is to detect the anomalies between mine surface and soil from variation of reflected/emitted thermal radiation. In this thesis, various types of anomaly detection techniques of IR are investigated and the feasibility of these techniques for use in landmine detection is analysed. Additionally, effects of parameters for algorithms are compared and the parameters are optimized for increasing detection accuracy. Furthermore, fusion of the algorithms is performed to reduce False Alarm Rate (FAR). We also prepare an experimental setup to reflect the effects of environmental changes on FLIR imagery recording. Soil and various types of landmine mock-ups are also examined in this setup. Finally, all anomalies are mapped into local coordinate space for indicating possible landmines locations.

Forward-Looking Infrared Imagery for Landmine Detection
Bayram, Aylin; Akar, Gözde (2017-04-13)
Infrared imagery is widely used in many applications in both civilian and military areas. In landmine detection, the goal is to detect the anomalies between mine surface and soil from variation of reflected/emitted thermal radiation. In this study, various types of anomaly detection techniques of IR are investigated and the feasibility of these techniques for use in landmine detection is analyzed.

Imaging infrared seeker design
Ünal, Ahmet; Çakır, Serhat; Department of Physics (2014)
The subject of this study is the design of an imaging infrared seeker for aerial targets. Firstly the radiant power of the target was discussed and optical design of seeker lenses were done with ZEMAX Optical Design Software considering the MTF (Modulation Transfer Function) values, optical path ifferences, distortions and detection range calculations. After that, detection range calculations and simulation results of the optical system were presented. Before lock on range calculations, spectral band of the...
Dim point target tracking in infrared image sequences with low SNR
Güler, Zahide Selin; Vural, Elif; Department of Electrical and Electronics Engineering (2016)
Dim point target tracking in infrared (IR) images has been an active research area especially in military fields. Due to the long distance from IR sensors, target appears as a dim moving point hidden in a heavily cluttered background and causes the Signal to Noise Ratio (SNR) to be very low. We present a tracking algorithm based on Particle Filters (PF), which estimates the target position by using both brightness level and motion model measurements. A target candidate list for the presented PF algorithm is...
Lithologic discrimination and mapping by aster thermal infrared imagery
Okyay, Ünal; Süzen, Mehmet Lütfi; Kaymakcı, Nuretdin; Department of Geological Engineering (2012)
In conventional remote sensing, visible-near infrared (VNIR) and shortwave infrared (SWIR) part of the electromagnetic spectrum (EMS) have been utilized for lithological discrimination extensively. Additionally, TIR part of the EM spectrum can also be utilized for discrimination of surface materials either through emissivity characteristics of materials or through radiance as in VNIR and SWIR. In this study, ASTER thermal multispectral infrared data is evaluated in regard to lithological discrimination and ...
High operating temperature mid-wave infrared HgCdTe photodiode design
Yurtseven, Eray; Kocaman, Serdar; Department of Electrical and Electronics Engineering (2019)
Infrared focal plane arrays are critical components in many of the military and civilian applications for advanced imaging systems. HgCdTe is one of the most widely used infrared detector material. An important issue with this material for thermal imaging system is the operating temperature as it determines cryocooler crucial characteristics, namely power comsumption and device lifetime. Therefore, there is an effort towards to operate at higher temperatures, but performance characteristics need to be caref...
