基于跟踪任务需求的火控雷达网抗分选控制策略

摘要

针对火控雷达信号极易被敌方侦察系统分选识别的问题，提出一种基于跟踪任务需求的抗分选控制策略。首先通过跟踪精度描述了火控雷达对目标的跟踪任务需求；然后将间歇开机与雷达组网相结合，在满足门限精度的条件下，对火控雷达网内的雷达进行轮换开机控制；最后对侦察系统的信号分选部分进行了仿真建模，通过分选成功率验证控制策略的有效性。结果表明，该策略在保证跟踪需求的前提下，使网内雷达信号的抗分选性能得到了提高。%The fire-control radar's signal is easily to be sorted and identified by the enemy reconnaissance system .Aiming at this problem,a radiation control strategy is proposed to improve the counter-sorting performance based on tracking requirement .Firstly,the tracking requirement of the fire-control radar to a target is described as the tracking accuracy .Then intermittent work is combined with radar network,and radars of the network are controlled through work rotation on the condition that the threshold tracking accuracy is kept .Finally,the simulation model of reconnaissance system's signal sorting is established,and the effectiveness of control strategy is verified .The results show that,with the radiation control strategy,the counter-sorting performance of the fire-control radars in the network is increased while keeping target tracking .
