Maximum Complexity Principle prediction of battlefield electromagnetic signal environment

CHEN Hang-yong1,2 ZHANG Dian-zong2 WANG Yi2 XIAO Chang-da2 CHEN Hai-jian3(1.PLA Unit92493Post-doctoral scientific research workstation,Qinghuangdao,Hebei066001,China;2.PLA Unite91404,Qinghuangdao,Hebei066001,China;3.PLA Unite73639,Xiamen,Fujian361003,China)  
Distribution status prediction of battlefield electromagnetic environment is necessary precondition when we construct complex electromagnetic environment for electronic countermeasure training,.However,the present analytical method can not be used to predicate electromagnetic environment distribution status,which is lack of theoretic basis and operational standard of constructing,controlling and e-valuating electromagnetic environment.In order to overcome this,the conception of entropy is used to predicate spectrum distribution in battlefield electromagnetic environment.Firstly,present research status is reviewed on complexity of battle-field electromagnetic environment based on entropy.With the constitution theory,the constitution and complexity of battlefield electromagnetic signal environment are investigated.The complexity computation formulas are proposed for represen-ting time,frequency and space occupation difference.Then,with maximum com-plexity Principle,frequency occupation distribution function of battlefield electro-magnetic signal environment is predicated under the condition of battlefield electro-magnetic compatibility.Lastly,simulation results are given,which match the theo-retical computation well.
