Angle random walk (ARW) is a critical noise component of a typical gyroscope alongside with bias instability noise. ARW has dominant effects especially in short-term accuracy. The measurement uncertainty degrades with the deterioration in ARW resulting in the lowered overall gyroscope accuracy. Many inertial navigation applications such as satellite control and gyro-compassing require low ARW. For an interferometric fiber optic gyroscope, lowest detectable rotation is proportional to scale factor of sensor and inversely proportional to optical bandwidth of light source used in the gyroscope. In this study, using a novel pump laser control closed-loop method, gyroscope performance is able to significantly enhance including signal-to-noise ratio (SNR). Fiber optic gyroscope includes an Yb-doped amplified spontaneous emission (ASE) source with broad emission spectra of 15 nm bandwidth used as light source in order to improve gyroscope sensitivity. The final ARW performance is about 0.008 degrees/root hr for a fiber coil of 150 m length.

Uncertainty in Nonlinear SDoF Response Due to Long-Period Noise of Accelerograms Akkar, Dede Sinan; Guelkan, Polat; Kale, Oezkan (2009-07-01) The behavior of nonlinear oscillator deformations due to the long-period noise in strong ground motions is investigated. Inelastic spectral and residual displacements (SDIE and SDR, respectively) are selected to represent the nonlinear deformations of single-degree-of-freedom (SDoF) systems. Within this context, the interaction between these deformation demand parameters and high-pass filtering that is used for removing the long-period noise is examined. Analyses indicate that the high-pass filter values ca...
Surface Recombination Noise in InAs/GaSb Superlattice Photodiodes Tansel, Tunay; Kutluer, Kutlu; Muti, Abdullah; Salihoglu, Omer; Aydinli, Atila; Turan, Raşit (2013-03-01) The standard Schottky noise approach alone is not sufficient to describe the noise mechanism in an InAs/GaSb superlattice photodetector at reverse negative bias. The additional noise identified appears at surface activation energies below 60 meV and is inversely proportional to the reverse bias. In order to satisfactorily explain the experimental data, we hereby propose the existence of a surface recombination noise that is a function of both the frequency and bias. The calculated noise characteristics inde...
Noise Estimation for Hyperspectral Imagery using Spectral Unmixing and Synthesis DEMİRKESEN, CAN; Leloğlu, Uğur Murat (2014-09-25) Most hyperspectral image (HSI) processing algorithms assume a signal to noise ratio model in their formulation which makes them dependent on accurate noise estimation. Many techniques have been proposed to estimate the noise. A very comprehensive comparative study on the subject is done by Gao et al. [1]. In a nut-shell, most techniques are based on the idea of calculating standard deviation from assumed-to-be homogenous regions in the image. Some of these algorithms work on a regular grid parameterized wit...
Parameter estimation of multicomponent micro-doppler signals / Yıldız, Hüseyin; Severcan, Mete; Department of Electrical and Electronics Engineering (2014) Vibrating and rotating parts on a radar target is known to generate frequency modulated echo signal which is called micro-Doppler signal. Micro-Doppler signals are commonly modeled as the sum of sinusoidally modulated signals and the parameters, such as amplitude, frequency, phase, of these modulations are useful in the identification of these targets. In this thesis, the parameters of micro-Doppler signals from helicopter targets are estimated for the classification of the helicopters. Time-frequency analy...
Two-dimensional transient dynamic response of orthotropic layered media Abu Alshaikh, Ibrahim; Turhan, Dogan; Mengi, Yalcin (Springer Science and Business Media LLC; 2006-12-01) In this study, two-dimensional transient dynamic response of orthotropic plane layered media is investigated. The plane multilayered media consist of N different generally orthotropic, homogeneous and linearly elastic layers with different ply angles. In the generally orthotropic layer, representing a ply reinforced by unidirectional fibers with an arbitrary orientation angle, the principal material directions do not coincide with body coordinate axes. The solution is obtained by employing a numerical techn...
