A visual simulation system of fragment warhead missile attacking F-16C ''Falcon'' battle plane based on simulation and virtual reality technology is put forward. Firstly, the overall design of visual simulation of missile attacking F16 battleplane is implemented, and all functions of each module are demonstrated in detailed. Then 3D models in virtual battle field are optimized by level of detai...

Aperture coupling is the main coupling mode through which electromagnetic pulse (EMP), ultra wideband (UWB) and high power microwave (HPM) can disturb or damage electronic equipments of the missile enclosure. To get knowledge of the coupling effects of apertures with different shapes and positions, coupling processes of HPM into the missile enclosure are investigated. The simulation results ind...

This paper presents a nonlinear observer design method for acceleration control of tail-controlled Skid-to-Turn missiles. A nonlinear observer for wind angles (angle of attack and sideslip angle) is designed using a parametric affine missile model developed by the authors. Using the estimated wind angles, a desired acceleration tracking performance can be obtained by a nonlinear control based o...

By P. K. Menon and E. J. Ohlmeyer Abstract Recent threat assessments by the US Navy have indicated the need for improving the accuracy of defensive missiles. This objective can only be achieved by enhancing the performance of the missile subsystems and by finding methods to exploit the synergism existing between subsystems. As a first step towards the development of integrated design methodolog...

According to the working mode of the ballistic missile warning radar (BMWR), the radar return from the BMWR is usually sparse. To recognize and identify the warhead, it is necessary to extract the precession frequency and the locations of the scattering centers of the missile. This article first analyzes the radar signal model of the precessing conical missile during flight and develops the spa...

The principle of dynamic programming is used to develop a digital computer software package for determining for each of several subsystems the optimal numerical integration algorithm from among given candidate techniques. As by-products, the corresponding optimal step sizes and error contributions of the subsystems are provided to the user. The deveiloped program minimizes subsystem sum-squared...

The traditional three-loop autopilot[11] suffers from coupling in pitch, yaws, roll channel as well as degraded performance due to huge aerodynamic uncertainties. Sliding mode control is applied to design autopilot for skid-to-turn missile (STT) missile systems to overcome the above stated difficulties. The design has two steps. The first step involves feedback linearization and the second stag...

The equations of motion of a missile under the air drag effects are constructed. The modified TD88 is surveyed. Using Lagrange’s planetary equations in Gauss form, the perturbations, due to the air drag in the orbital elements, are computed between the eccentric anomalies of the burn out and the reentry points Ebo, 2π −Ebo , respectively. The range equation is expressed as an infinite series in...

Enclosed weapon bays on modern aircraft interfere with prelaunch, Flight Termination System verification during training test launches. Range safety personnel need to verify the functionality of the flight termination system prior to missile launch. The missile telemetry RF is highly attenuated when the aircraft missile bay doors are closed, limiting the range for which the aircraft can fly dur...

Cross-eye jamming is an on-board ECM technique that may potentially be applicable to platform self-protection against missiles that employ fully active radars. This paper explores one aspect of amplitude-modulated cross-eye jamming in missile defense. In this analysis, the seeker in the missile is assumed to contain a monopulse tracking antenna and an exact monopulse processor. It will be seen ...
