电子战条件下飞机敏感性分析及其减缩技术

Aircraft Susceptivity Analysis and Decrease Methods Under the Conditions of Electronic War

介绍了电子战和飞机生存力及敏感性的内涵,构建了飞机敏感性量化评价指标层次体系。定性分析了电子干扰对雷达探测概率和导弹脱靶距离标准差的影响,并以算例说明了干扰效能的增大会引起导弹制导精度的降低和脱靶距离的增大,从而得出:电子干扰对飞机的敏感性和生存概率有重要的影响。引入了干扰效能因子的概念,并分析了将干信比J/S作为一种干扰效能因子考虑的可行性及优点。最后给出了降低飞机敏感性的电子战措施。

The concept of electronic war and aircraft survivability and susceptivity is introduced,a quantitative evaluation hiberarchy system of aircraft survivability is designed.The effect of electronic jamming to radar detection probability and the standard deviation of missile missing distance is qualitative analyzed,the calculation example shows the increase of jamming efficiency causes the reduction of the missile guide precision and the increase of missing distance,which indicates that the electronic jamming makes great influence to aircraft susceptivity and survivability.The jamming efficiency factor is brought forward as a new concept,and the ratio proved to be looked as one type of jamming efficiency factor.The electronic countermeasure methods of reducing the aircraft susceptivity are given at the end.
