高空无人侦察机生存力仿真研究

文章分析了高空无人侦察机的敏感性、易损性与生存力之间的关系.建立了高空无人侦察机生存力模型.通过仿真对高空无人侦察机生存力及主要影响因素--高空无人侦察机的航路捷径、飞行高度、飞行速度及雷达散射截面积RCS进行了研究.仿真结果表明,高空无人侦察机生存概率随航路捷径的增大、飞行高度的增高、飞行速度的提高及RCS的减缩呈阶梯状增加;而在相同生存概率的条件下,上述的生存力增强措施均能增加高空无人侦察机的突防距离.

Numerically Simulating Survivability of High-Altitude Unmanned Reconnaissance Aerial Vehicle(URAV)

Section 1 of the full paper,after analyzing in some detail the relationships among the susceptibility,vulnerability and survivability of the high-altitude URAV,establishes its survivability model.Section 2 explains in some detail how to implement the numerical simulation of the survivability model and then explains the factors of influenee,including the shortcut flight course,flight altitude,flight velocity and radar cross section(RCS)of the URAV.The block diagram,as shown in Fig.1,gives the simulation flow chart of survivability.Section 3 presents two numerical examples.The numerical results,given in Figs.2 through 5,and their analysis show preliminarily that the survivability probability of the URAV increases with increasing shortcut night course,increasing flight altitude,increasing flight velocity and decreasing RCS.The numerical results,given in Figs.6 through 9,show preliminarily that,with the same survivability probability,the above-mentioned survivability-increasing measums can increase the penetration distance of the UBAV.
