    10  Study on ECM Efficiency of Multiple Jamming against Multi-Stage Radar System
    海湾战争标志着“陆海空天电”联合作战模式的兴起,在这种形式的战争中,电子战起着关键性的作用。电子对抗与反对抗的战术技术水平已经成为制约高技术局部战争胜负的关键因素,而电子战本身也已从单一装备间的对抗,发展到系统对系统、体系对体系间的对抗。因此,单一武器平台或局部的仿真系统不再能够满足对整个战场作战态势分析的需要,必须通过单元仿真模型集成出一种综合电子战仿真系统,其中,对作战效能的分析是不可或缺的。  在综合电子战系统中,一般以空袭方的对地攻击效果和防空方对进攻编队的毁伤率来直观
