对典型作战场景中雷达制导导弹威胁下的飞机敏感性进行了研究,分别从导弹发射和命中2个方面,建立了远距离支援干扰(SOJ)和自卫干扰(SPJ)条件下的飞机敏感性模型。首先分析了在典型电子对抗措施(ECM)和电子抗干扰措施(ECCM)条件下的雷达探测距离;其次提出了用于评价欺骗干扰的有效时间模型,结合典型制导律,建立了不同干扰条件下导弹命中分析的仿真模型;最后对不同干扰条件下的飞机敏感性进行了仿真实验。结果表明:电子干扰一定程度上能够降低非隐身战机的敏感性,但是对于低雷达散射截面(RCS)或者采用先进抗干扰措施的武器系统而言,电子干扰对飞机敏感性降低的作用有限甚至有害。研究结果对现役飞机通过电子干扰降低敏感性以及对在研飞机的敏感性设计具有一定的参考意义。
The sensitivity of aircraft under the threat of radar-guided missiles in a typical combat scenario was studied. The sensitivity models of aircraft under SOI and SPJ were established respectively from two aspects of missile launch and hits. . Firstly, the radar detection range under typical ECM and ECCM conditions is analyzed. Secondly, an effective time model for evaluating deceptive interference is proposed. Combined with the typical guidance law, the radar detection range is established under different interference conditions Missile hit analysis simulation model; Finally, the simulation experiments under different interference conditions of the aircraft sensitivity. The results show that the electronic jamming can reduce the sensitivity of non-stealth fighter to a certain extent, but the effect of electronic jamming on the reduction of aircraft sensitivity is limited or even harmful to low radar cross section (RCS) or weapon system adopting advanced anti-jamming measures . The results of this study are of some reference value for the active aircraft to reduce the sensitivity through electronic interference and to design the sensitivity of aircraft under study.
