Missile design is often separated into distinct subsystems such as seeker stabilization, target detection and tracking, guidance, and autopilot. The miss distance strongly depends on proper integration of those critical subsystems and the prototyping of visually guided missiles. A low-cost integrated solution based on a PC running Matlab is an attractive option to test new ideas on guidance, co...
2 INTRODUCTION The guided missile provides military forces with the capability to deliver munitions rapidly and precisely to selected targets at a distance. This capability establishes an effective means to conduct a wide variety of military missions that range from denying the enemy communications or supply routes, to establishing air superiority, to performing anti-ship cruise missile or ball...
Apparent design breakthroughs in short-range missile defense systems such as Theater High-Altitude Air Defense (THAAD) have prompted questions about the legality of such systems under the 1972 Antiballistic Missile (ABM) Treaty. Prominent physicists have used computer “footprint” methodology to prove that if engineered to specifications, THAAD might exceed ABM Treaty performance limits banning ...
The Missile, Research, Development and Engineering Center, MRDEC, of the U.S. Army Aviation and Missile Command, AMCOM is developing and demonstrating tele-operated missile systems that provide many of the capabilities that the Army has stated it needs. These capabilities include flexible mission planning, improved Identification Friend or Foe, minimum collateral damage, and precision hit. The ...
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...
