Multiblock grid generation for missile configurations

Multiobjective missile rescheduling problem Silav, Ahmet; Karasakal, Esra; Karasakal, Orhan; Department of Industrial Engineering (2017) In this thesis, we address dynamic missile allocation problem for a naval task group (TG). We consider rescheduling of surface to air missiles (SAMs) in response to disturbances during the engagement process where a set of SAMs have already been scheduled to a set of attacking anti-ship missiles (ASMs). To produce an updated schedule, we propose mathematical models that consider efficiency of air defense and stability of the schedule. In the first part of thesis, we present a new biobjective mathematical mo...
Polynomial trajectory shaping guidance algorithm for multi-missile salvo attack Bingöl Taştankaya, Neşe Başak; Tekinalp, Ozan; Department of Aerospace Engineering (2018) In this thesis, a guidance algorithm is proposed which aims to control impact time via polynomial shaping of the missile trajectory and missile flight path angle. The main motivation of the trajectory design, which is convenient for impact time control, is its application to multiple missile engagement situations. In the first part of the study, a planar engagement geometry is considered. The trajectory of the missile is defined as a third order polynomial function of downrange. The coefficients of the poly...
Short range thrusting projectile tracking Bilgin, Ozan Özgün; Demirekler, Mübeccel; Department of Electrical and Electronics Engineering (2012) Short range thrusting projectiles are one of the various threats against armored vehicles and helicopters on the battlefield. Developing a countermeasure for this kind of projectiles is very crucial since they are vast in number and easy to operate on the battlefield. A countermeasure may consist of fire point prediction of the projectile and attack the launcher of it, or it may be the impact point prediction of the projectile and apply a hard-kill counter measure on its way to the ally target. For both of ...
An Efficient Iterative SIC for Full-Duplex SC-FDE Radio under Hardware Impairments Kurt, Anıl; Salman, Murat Babek; Güvensen, Gökhan Muzaffer (2021-06-01) In this study, a novel iterative turbo digital self interference cancellation (DSIC) algorithm is proposed to eliminate remaining self interference (SI) signal, which is contaminated by signal of interest (SoI), subject to time varying SI channel. SoI creates a noise floor for the estimation of SI signal; hence, estimation accuracy significantly degrades. In order to improve the estimation accuracy, it is proposed that for each block, SoI is decoded via signal decomposition based on generalized memory polyn...
Decomposition techniques in energy risk management Sürücü, Oktay; Gaygısız Lajunen, Esma; Department of Financial Mathematics (2005) The ongoing process of deregulation in energy markets changes the market from a monopoly into a complex one, in which large utilities and independent power producers are no longer suppliers with guaranteed returns but enterprisers which have to compete. This competence has forced utilities to improve their efficiency. In effect, they must still manage the challenges of physical delivery while operating in a complex market characterized by significant volatility, volumetric uncertainty and credit risk. In su...
