The use of export controls to regulate the supply of major conventional arms systems and materials associated with weapons of mass destruction (WMD) has long been a central component of nonproliferation efforts. But how well are US and multilateral efforts to control the export of advanced weaponry and sensitive dual-use technologies working? Iraq’s ability to purchase key components for its WM...
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...
In this paper, a new guidance method for surface to surface ballistic missiles without mandatory engine cut-off will be presented. The complexity of solid fuel engine cut-off demands a comprehensive method for guiding these missiles. In the method presented in this paper, a certain guidance law is applied such that by transmitting appropriate commands to the control system, by changing the miss...
In this paper, a robust control law is proposed, based on Lyapunov’s theory and sliding mode control theory, in order to track the angle of attack in nonlinear longitudinal dynamics of a missile. It is assumed that there are unmatched uncertainties in the nonlinear systems. In the proposed algorithm, the controller gains are optimized by Particle Swarm Optimization (PSO) algorithm. For...
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...
Design and Simulation of an Infrared Jammer Source for an Infrared Seeker M. R. Mosavi; M. Asadpour; H. A. Ameri Department of Electrical and Computer Engineering, Behshahr University of Science and Technology ABSTRACT Infrared jammer source is intended for active protection of helicopters against guided missiles with IR homing devices. The majority of such known stations are intended for suppr...

This report presents a multivariable controller design for a generic missile travelling at hypersonic speed. The controller is based on the theory of optimal control, and the solution is provided by a feedback controller known as a Linear Quadratic Regulator (LQR) for tracking the demands (lateral acceleration and roll rate) as closely as possible while keeping the actuator efforts (for deflect...
This paper is concerned with the application of advanced Linear Parameter-Varying (LPV) techniques to the global control of a missile. The LPV technique considered in this paper is an extension of the standard H 1 synthesis technique to the case where the plant depends aanely on a time-varying vector (t). Working in the class of LPV plants, the proposed methodology produces an LPV controller. T...
