Radar systems have important roles in both military and civilian applications. As the capabilities increase in terms of range, sensitivity and the number of tracks to be handled, the requirement for automatic target recognition (ATR) increase. ATR systems are used as decision support systems to classify the potential targets in military applications. These systems are composed of four phases, which are selection of sensors, preprocessing of the radar data, feature extraction and selection, and processing of features to classify the potential target. In this study, we focus on the classification phase of ATR and develop a novel multiple criteria classification method based on modified Dempster Shafer data fusion algorithm. Ensemble of classifiers are used as a classification algorithm. They are treated as the state of the art technology for classification in which each single classifier is trained separately, and then the results of them are combined through several fusion algorithms. Support vector machine and neural network are employed as probabilistic classifiers in ensemble. Each non-imaginary dataset coming from multiple heterogeneous sensors is classified by both of the classifiers in the ensemble, and the classification result that has higher accuracy ratio is chosen for each of the sensor dataset. After getting probabilistic classification of targets by different sensors, modified Dempster Shafer data fusion algorithm is used to combine the sensors’ results to reach the final classification of the targets. In this talk, a number of classification algorithms are compared with the proposed algorithm and the results will be discussed.

Multi-Aspect Data Fusion Applied to Electromagnetic Target Classification using Enetic Algorithm
Sayan, Gönül (Kluwer Academic Publishers, 2002-01-01)
Electromagnetic target detection and classification is an important problem relevant not only to military applications but also to civilian use. In the problem of a breast tumor detection and identification [1], for instance, the main concern is accuracy. In the case of the recognition of a military target such as an aircraft or a ship, on the other hand, speed of classification is as important as the accuracy of the decision as such a decision should be made within a fraction of a second. For...

SWIR objective design using seidel aberration theory
Aslan, Serhat Hasan; Yerli, Sinan Kaan; Keskin, Onur; Department of Physics (2016)
Optical systems are used for increasing the situational awareness and Intelligence, Surveillance and Reconnaissance (ISR) capabilities for military purposes. MWIR (Midwave infrared) and LWIR (Long wave infrared) waveband informations are the first two wavebands information in the atmospheric transmission window that are harnessed in military night vision optical systems. Another candidate of these operable wavebands is the SWIR (Shortwave infrared). Shortwave infrared (SWIR) imaging is an extension of Near ...
Zero crossing counter for accuracy improvement of FMCW range detection
Kurt, Sinan; Demir, Şimşek; Hizal, Altunkan (2008-01-01)
For civil and military purposes FMCW radars are widely used. The theoretical background is well-established. Nevertheless, improvement of various aspects of these radars is still required. Signal processing is one of the crucial points of the system which determines the capabilities of the radar. In this study a zero crossing detector implementation, which can be efficiently used for target detection and range calculation in short range FMCW range detector is proposed. The duration between consecutive zero-...
