This paper addresses the problem of bearings only and bearings and extent tracking for closed loop missile guidance systems using particle methods compared with derivative free methods. Lack of observability is a typical phenomenon for the bearings only tracking problem. We demonstrate that exploiting angular extent information does help mitigating the lack of observability issues. The simulati...

EXECUTIVE SUMMARY This paper describes how an Enterprise infrastructure is supporting agility on two ARPA initiatives namely, RASSP (Rapid prototyping of Application Specific Signal Processors), and AM3 (Affordable Multi-Missile Manufacturing). The two programs involve several large enterprises linked electronically to form virtual enterprises and aiming to address the issues raised by the cons...

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 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 ...

A differential game guidance law for an endoatmospheric interceptor missile steered by aero fins and reaction jets is developed in this paper with bounded controls. For a low-altitude endoatmospheric interceptor, the propellant of the reaction-jet control system (RCS) is restricted by the missile configuration. Considering propellant limits, the effect of the RCS thrust on homing performance is...

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 the communication mechanisms of a missile engagement simulator are modelled and analysed. The simulator is developed as a testing platform for missile guidance and control algorithms. The simulation uses concurrency and remote execution concepts to enhance performance. Coloured Petri nets are a well suited formal approach for modelling and analysis of these concepts. Design/CPN is...
