GPS is a radio navigation system that provides accurate navigation signals to any place on Earth. Although GPS was originally designed for military applications, GPS has also been used in many civilian applications. The reliability of GPS receivers and the availability of GPS signals have become crucial in the fast-growing use of GPS in military and(More)
In spectroscopy, for material detection and identification applications, spectral libraries are used as reference databases. In spectral libraries, there are spectral reflectance signatures of many materials in electro-optical and optical wavelengths. Sometimes, in spectral libraries, different subclasses of the same materials are included. In material(More)
This paper proposes a general approach to detect the presence of deceptive counter measures such as RGPO or VGPO. The method which is based on the Kalman filter lays its foundation on drift between Doppler measurement and the Doppler information obtained from the range measurement of a target in track. By measuring this drift by Mahalonobis distance metric(More)
Frequency Diverse Array (FDA) concepts, first introduced in 2006, present a novel approach to electronic beam steering. FDA differs from other conventional arrays in that it applies a small frequency increment to the center frequency for each individual array element creating range, angle, time and frequency offset dependent beam pattern. A conceptual(More)
Missile warning receivers are electronic support systems which are widely used for the protection of fixed and rotary wing aircraft against infrared guided missiles. Proposed methodology for the detection of missile threats in missile warning receivers depends upon the estimation of background from consecutive image frames. By removing the estimated(More)
In the color cognition process of a scene, there is no use of the atmosphere, surface reflectance and illuminant interaction. Therefore, the color perception is blind. The color perception in human brain is directly related to the response of retinal photodetector tissues. Are there only three detectors in the retina; Red, Green, Blue detectors; or are(More)
Extraction of scene components is one of the main problems in the analysis of remotely sensed hyperspectral images. Scene components can be identified by applications of blind methods. In this study, two novel applications of Canonical Correlation Analysis (CCA) are proposed for the blind analysis of hyperspectral images.
The phenotypic properties of the livings are dependent on lots of genes and the nucleotide sequences which control that genes in their genomes. One of these control tasked nucleotide sequences is promoter regions. It is seen that these regions have complexity in the way of nucleotide sequencing. In this paper, the complexity of the promoter regions of human(More)
