摘要
为研究电子干扰掩护条件下,隐身飞机突防战术作战效能,在计算某型隐身飞机动态雷达散射截面积(Radar Cross Section,RCS)的基础上,研究隐身飞机突防对雷达探测性能的影响。首先,通过雷达坐标系与飞机机身坐标系转换矩阵,计算不同时刻随着飞机位置变化的雷达照射角度。然后,用软件构建某型隐身飞机表面三角面元模型,采用物理光学法(Physical Optics,PO)仿真计算飞机随时间变化的动态RCS。最后,针对隐身飞机在支援干扰飞机掩护下的突防模型,进行计算机仿真,并分析不同时刻防御方雷达探测性能变化情况。仿真结果表明,通过合理设置远距离支援干扰飞机航线,选择恰当自卫干扰时机,可有效提高隐身飞机突防效果。研究结果对我军开展隐身与反隐身作战具有一定的理论指导意义。
In order to study the tactical operational effectiveness of stealth aircraft penetration,the influence of penetration on radar detection performance is studied based on the calculation of dynamic radar cross section(RCS)of a stealth aircraft.Firstly,the radar illumination angles at different times with the change of aircraft position are calculated by the transformation matrix between radar coordinate system and aircraft fuselage coordinate system.Then,the surface triangular panel model of a stealth aircraft is built by software,and the dynamic RCS of the stealth aircraft with time is calculated by physical optics(PO)simulation.Finally,according to the penetration model of stealth aircraft under the support of jamming aircraft,computer simulation is carried out,and the detection performance change of defense radar at different times is analyzed.The simulation results show that the penetration effect of stealth aircraft can be improved by reasonably setting the route of long-distance support jamming aircraft and choosing the proper time of self-defense jamming.The research results have certain theoretical guiding significance for our army to carry out the operation of stealth in anti-stealth.
