Missile pulmonary emboli are rare sequelae of traumatic entry of projectile missiles-generally bullets or bullet fragments-in which access to the systemic venous circulation is established by the missile, making it possible for the missile to migrate to the pulmonary arteries. In the case introduced here, a 24-year-old male presented to the ER with a gunshot wound to the abdomen. In the early c...

The interception of a maneuvering antisurface missile, as in ballistic missile defense and ship defense scenarios, is formulated as an imperfect information, zero-sum, pursuit-evasion game with a state constraint imposed on the evader. Assuming that the perfect informationversion of the gamedoes not yield a successful result for the defense, the solution of this game is in mixed strategies. The...

Greyscales is a method for producing estimates of guided missile miss distance and missile warhead probability of kill. The associated computer code has been written to be portable and capable of being incorporated into a variety of simulations. The code has already been integrated into the Weapon Systems Division MECA and DUEL missile engagement simulations. It can also be integrated into larg...

Missile pose estimation in terminal guidance refers to the technique of estimating missile position and attitude by matching seeker images with pre stored reference images during the terminal phase of missile flight. This paper presents a method for estimating the position and orientation of the missile with respect to a known object using point correspondences between seeker and reference imag...

Aiming at the poor reliability of targets destroy for single base surface-to-air-missile weapon system, and the existing shortcomings of anti-destroying ability for missile networking system, this paper research on system level surface-to-air-missile defense system network features. On the analysis of the missile launching area boundary, the kill probability, the operational time and threat lev...

This paper shows; that, in some conditions we can obtain the exact solution for a missile and an aircraft differential games which minimizes and maximizes the essential pay-off of the problem: the miss distance, without employing any linearized approximation. The idea of our method is, by starting from the aircraft one-sided optimal control solution against a PNG missile, which maximizes the mi...

Lethality evaluation tests of anti-armor missile systems require flight-test of tactical missiles against threat targets under highly controlled impact conditions. Variables such as terminal dive angle, impact velocity, missile orientation at impact, hit-point on the target, and shot-line through the target all must be carefully controlled and documented to properly evaluate and analyze the dam...

The development of modern air defense missile systems requires robust simulations to adequately place margins on hardware and software design. Coupled with this is the need to accurately model surface reflections that constitute clutter to the missile system. A thorough understanding of these reflections is becoming increasingly important as the air defense threat evolves from large, high-altit...

Powerful nonlinear approaches for missile autopilot design have recently emerged in the literature, which have the potential to deliver improved missile performance. However, the lack of computational methods has made it difficult for the practicing engineers to exploit these techniques in routine applications. Another factor that has slowed their application is that the missile models are gene...

Infrared cameras can detect the heat signatures of missile plumes in the mid-wave infrared waveband (3-5 microns) and are being developed for use – in conjunction with advanced tracking algorithms – in Missile Warning Systems (MWS). However, infrared imagery is also liable to contain appreciable levels of noise and significant levels of thermal clutter, which can make missile detection and trac...
