The Study On The Strategy And Capacity In Co-operative Engagement Of Missile Defense System

With the continuous development of missile weapon system,single countermeasure in missile attack and defense has been replaced by cooperative countermeasure.Cooperative countermeasure of missile defense system will give full play to interception missile,guidance radar and other combat units by coordinating the coupling effect of each part,thus reaching the effect of one plus one is greater than two.In the operation of missile defense system,elements of deployment position,interception capability and the earliest launch time of interception system all matter greatly,therefore it is essential to conduct an analysis on all factors influencing combat effectiveness with a logical and highly operative evaluation and analysis method.In this paper,an evaluation of combat effectiveness in defense zone is proposed based on reachable set.An evaluation of combat effectiveness of cooperative countermeasure under a various operational environments is realized through quantitative and qualitative analysis of defense zone and study of different factors involved.Major parts are listed as follow.A reachable set model of missile defense system is established and researches are conducted to study different reachable sets under various parameters.Based on previous studies,maximum and minimum ranges come after hierarchical modeling of interception reachable set and analysis with dimension reduction method.Considering time limit in defense system,time-related reachable set model is set up to analyze how first-found-time influences time-related reachable set.Furthermore,distance-related reachable set model is presented for the first time according to the radar's detection range constraints in missile defense system.Therefore,influence of radar's maximum detection range on range-related reachable set is analyzed for future modeling and analysis.Model of missile defense system in defense zone is set up and studies of defense zone under different combat simulations are conducted as well.Defense zone is strictly defined based on reachable set model and computing model of defense zone is established accordingly.For ballistic attack targets of the fixation of both launching point and the absolute speed of shutdown point,when targeting high trajectory and low trajectory clusters,analyses of influence on defense zone imposed by interception's deployment location,kinetic energy of interception and its earliest launching time are conducted respectively,obtaining analysis of combat effectiveness.Cooperative combat ability of missile defense is studied and analyzed.Based on the studies of operations in position with single interception and single radar and several typical case studies,analysis of how cooperative countermeasure influences the structure and area of defense zone in position with multiple interceptions and radars.Distributive parallel experiment management system is designed.A large amount of simulation data required analyzing reachable set and defense area mainly comes from simulation target practices.In addition to offensive missile model and interception missile model,a highly effective and stable platform of simulation experiment is also essential for the simulation of missile defense system.In this paper,a distributive and parallel experiment management system is designed and developed based on CPSE simulation platform which was self-developed by National University of Defense Technology,effectively reducing the complexity of data simulation and shortening the simulation cycle.Research in this paper is conducted for practical need of general department for aerospace engineering.Computing model of reachable set,computing model of defense zone and distributive and parallel experiment management system have already been applied to certain simulation experiment system of aerospace industry,laying foundation for weapon system analysis and weapon specification design.Research results concluded in this paper are of important military and practical significance in providing technological reserve for the development of national missile defense system and reference for strategy-making of cooperative countermeasure in air defense and anti-missile as well.
