- W858316282 abstract "When considering advances in “smart” weapons it is clear that air-launchedsystems have adopted an integrated approach to meet rigorous requirements,whereas air-defence systems have not. The demands on sensors, stateobservation, missile guidance, and simulation for air-defence is the subject ofthis research. Historical reviews for each topic, justification of favouredtechniques and algorithms are provided, using a nomenclature developed to unify these disciplines. Sensors selected for their enduring impact on future systems are described and simulation models provided. Complex internal systems are reduced to simpler models capable of replicating dominant features, particularly those that adversely effect state observers.Of the state observer architectures considered, a distributed system comprisingground based target and own-missile tracking, data up-link, and on-boardmissile measurement and track fusion is the natural choice for air-defence. AnIMM is used to process radar measurements, combining the estimates fromfilters with different target dynamics. The remote missile state observercombines up-linked target tracks and missile plots with IMU and seeker data toprovide optimal guidance information.The performance of traditional PN and CLOS missile guidance is the basisagainst which on-line trajectory optimisation is judged. Enhanced guidancelaws are presented that demand more from the state observers, stressing theimportance of time-to-go and transport delays in strap-down systemsemploying staring array technology. Algorithms for solving the guidance twopointboundary value problems created from the missile state observer outputusing gradient projection in function space are presented.A simulation integrating these aspects was developed whose infrastructure,capable of supporting any dynamical model, is described in the air-defencecontext. MBDA have extended this work creating the Aircraft and MissileIntegration Simulation (AMIS) for integrating different launchers and missiles.The maturity of the AMIS makes it a tool for developing pre-launch algorithmsfor modern air-launched missiles from modern military aircraft." @default.
