researchers made significant progress toward developing naval-based theater missile defenses during the Clinton administration, the basic NMD architecture had no naval component because that administration sought actual deployments by 2005–2006. Once in office, the Bush administration was determined to accelerate progress on missile defenses, expand research and development efforts, accept a gr...

A method for the determination of the trajectory of a ballistic missile over a rotating, spherical Earth given only the launch position and impact point has been developed. The iterative solution presented uses a state transition matrix to correct the initial conditions of the ballistic missile state vector based upon deviations from a desired set of final conditions. A six-degree-of-freedom si...

An adaptive controller for the avoidance of an air combat missile utilizing a guidance law unknown to the target is introduced. The controls of the aircraft are determined at discrete instants using a receding horizon control scheme providing near-optimal feedback controls of the aircraft against a closing missile. The controls are optimized with respect to the expected final distance between t...

he rocket sled test facility at the Holloman Air Force Base in New Mexico provides a unique and valuable test venue for evaluating advanced missile technology at representative flight velocities. Recent failures at the facility underscore the inherent high-risk nature of supersonic sled tests and undermine their potential value to missile development programs. This article addresses one potenti...

Original scientific paper In this paper, a modified guidance and control sliding mode controller (MGCSMC) method is proposed in a guided missile system. The modified sliding mode controller (MSMC) algorithm is adopted to enable the missile to reach the desired target within a short period of time. The target always makes high manoeuvres when the missile is close to it. This issue has been treat...

The Joint Kill Chain Event (JKCE), designed by the Air Force’s Distributed Mission Operations Center (DMOC), provides an interesting case study for evaluation of simulated military training. JKCE places Army Air Defense Artillery Fire Control Officers (ADAFCOs) into an Air Force Control and Reporting Center (CRC) simulator. From the CRC, the ADAFCO leads an air missile defense scenario, protect...

Radar Seeker is used in missile system for detection and tracking a target. It will be integrated in the nose cone of the missile. During testing and launching of the missile all necessary important parameters and status of the seeker are collected for analysis to ascertain the health of the Seeker. Similarly the configuration and control of the seeker is to ensure the proper mode of operation ...

An integrated fuzzy guidance (IFG) law for a surface to air homing missile is introduced. The introduced approach is a modification of the well-known proportional navigation guidance (PNG) law. The IFG law enables the missile to approach a high maneuvering target while trying to minimize control effort as well as miss-distance in a two-stage flight. In the first stage, while the missile is far ...

The overload control of missile system is researched under the condition that the control direction is unknown. A nussbaum gain strategy is adopted to solve the unknown control direction problem for the linear model of missile motion of pitch channel . The backstepping technology and integral action are used to cope the system uncertainty. A novel type of control law, which is only consisted of...
