■ The U.S. Air Force is developing the airborne laser (ABL), whose mission is to engage and destroy theater ballistic missiles such as the SCUD while these missiles are in their boost phase. This mission capability requires high-energy laser propagation over long horizontal paths (200 to 300 km) through the upper atmosphere. To be effective in the presence of atmospheric turbulence, the ABL mus...

The National Strategy for Homeland Defense, published by the then U.S. Office of Homeland Security in July 2002, directs all U.S. government agencies to conduct vulnerability analyses of their sensitive systems. This policy applies to Department of Defense systems, including the simulation packages used to design and exercise national missile defense. Many, if not most, of the previous vulnerab...

Dual-band Infrared-based passive Missile Warning Sensors (MWS) are under development at USAF Wright Laboratory and other DoD labs to provide aircraft with cost-effective robust detection and tracking of Infrared Surface-to-Air Missile threats out to their maximum launch ranges. Typically, such sensors are limited by the presence of heavy background clutter, solar glints, and sensor noise which ...

Given the agreement among TCSCF, MP2, and MRMP methods, it is concluded that the structure of Si9H12 is symmetric, that dynamic correlation does not play a major role in determining the structure, and that DFT incorrectly predicts Si9H12 to be buckled.

Abstract This paper introduces a design method of hardware-in-the-loop simulation system applied to certain type image-guided missile. By studying the characteristics missile, working principle image-guidance is analyzed, mathematical scheme and are designed, mechanism RTX analyzed. Established real-time based on RTX+Windows, analyzed delay computer, simulated launch control flight motion simul...

Advanced shipboard radar systems will be required to detect, track and classify ballistic missile targets and re-entry vehicles, as well as perform traditional Anti-Air Warfare (AAW) operations. New Open Architecture Systems, including COTS hardware as well as open system software, are required to implement the necessary algorithms for successful missile defense. Lockheed Martin MS2 has been de...

The thesis deals with the guidance and control of a fighter aircraft in air combat. From the modeling perspective, the thesis formulates realistic air combat optimization problems and games in which inherent uncertainties of air combat are taken into account. From the solution perspective, the thesis develops on-line methods for the near-optimal feedback solution of the constructed models. The ...

Tracking a ballistic missile in its reentry phase is one of the missile defence challenges as these reentry vehicles penetrate with large aerodynamic loads and sudden decelerations from exoatmospheric to endoatmospheric phase. With the advent of anti-ballistic missiles, the main goal of missile defence systems is to track the reentry vehicle to locate them precisely for allowing midair altitude...

We describe JOINT DEFENDER, a new two-sided optimization model for planning the pre-positioning of defensive missile interceptors to counter an attack threat. In our basic model, a defender pre-positions ballistic missile defense platforms to minimize the worst-case damage an attacker can achieve; we assume that the attacker will be aware of defensive pre-positioning decisions, and that both si...
