Estimation of Target Velocity under Scarce Range Information for IR Guided Missiles

Babaoglu, Bugra Can
Kutay, Ali Türker
Missiles with only an infrared (IR) seeker can only be aware of the angular kinematics of the engagement - line of sight (LOS) angle and LOS angular velocity. However, in some occasions, missiles with IR seekers can be fed with low frequency range information, which is mostly provided by search radars. Nevertheless, it could be shown that, such scarcity in range information is not sufficient to solve the target-missile kinematics analytically. Still, certain numerical solutions can be applied in such situations. In this paper, a simple algorithm to estimate the velocity vector of a target using the range information provided by a search radar is proposed.

Optimization of vibration characteristics of a radar antenna structure
Baran, İsmet; Özgen, Gökhan Osman; Ciğeroğlu, Ender; Department of Mechanical Engineering (2011)
Radar antenna structures especially array antennas which are integrated onto structures of aerial vehicles are subject to dynamic structural and aerodynamic loads. Due to occurrences of these dynamic loads there will be certain dynamic deformations which affect the antenna’s performance in an adverse manner. The influence of deformations and vibrations are important on array antenna structures, since they cause a change in orientation of elements of the phased array antenna which affects the gain of the ant...
Measurement of jet fragmentation in PbPb and pp collisions at root s(NN)=2.76 TeV
Chatrchyan, S.; et. al. (2014-08-01)
The jet fragmentation function of inclusive jets with transverse momentum p(T) above 100 GeV/c in PbPb collisions has been measured using reconstructed charged particles with p(T) above 1 GeV/c in a cone of radius 0.3 around the jet axis. A data sample of PbPb collisions collected in 2011 at a nucleon-nucleon center-of-mass energy of root s(NN) = 2.76 TeV corresponding to an integrated luminosity of 150 mu b(-1) is used. The results for PbPb collisions as a function of collision centrality and jet transvers...
Numerical investigation of a Hawkmoth wing undergoing pure plunge motion in hover
Bektaş, Mürvet; Güler, Mehmet Ali; Kurtuluş, Dilek Funda (2019-09-20)
The aerodynamic phenomena of the flapping motion in hover mode is widely considered in micro air vehicle (MAV) applications. In this study, the aerodynamics of a three-dimensional rigid wing mimicked from the hawkmoth Manduca sexta is numerically investigated under pure plunge motion. The sinusoidal motion is provided with a user-defined function (UDF) to flap the wing, and the computational fluid dynamics (CFD) is used for the numerical analysis. This paper presents the effects of various parameters such a...
Multi-disciplinary design and optimization of air to surface missiles with respect to flight performance and radar cross section
Karakoç, Ali; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2011)
This study focuses on the external configuration design of a tactical missile based on maximizing flight range while minimizing the radar signature which is a crucial performance parameter for survivability. It is known that shaping of a missile according to aerodynamic performance may have significant negative effects on the radar cross section. Thus, the impact of the geometry changes on the aerodynamic performance and the radar cross section is investigated. Suggorage models for the flight range, control...
Calculation of flutter and dynamic behavior of advanced composite swept wings with tapered cross section in unsteady incompressible flow
Farsadi, T.; Hasbestan, J. J. (Informa UK Limited, 2019-02-16)
In this study, the aeroelastic stability and response of a swept composite wing in subsonic incompressible flow are investigated. The wing is modeled as an anisotropic tapered thin-walled beam with the circumferentially asymmetric stiffness structural configuration to establish proper coupling between bending and torsion. The structural model considers a number of nonclassical effects, such as transverse shear, material anisotropy, warping inhibition, nonuniform torsion, rotary inertia and three-dimensional...
