基于隐身飞机支援干扰的雷达效能评估

Radar Efficiency Evaluation of Stealth Aircraft Support-Jamming

针对现有评估方法没有考虑隐身性能与电子战能力有效结合对雷达探测效能影响的问题,提出了基于隐身飞机支援干扰的雷达效能评估方法。该方法利用平滑处理的全空域静态RCS值,结合雷达探测距离公式,仿真得到了隐身飞机全空域的雷达探测范围。然后分别以雷达最大和最小探测距离作为飞机的支援干扰距离,并在设置普通干扰机的干扰距离后,比较分析了三种干扰情况下雷达探测范围的变化。最后定义干扰压制率,对支援干扰的压制有效性进行了量化分析。仿真分析表明,隐身飞机支援干扰战术灵活,能够有效压制雷达探测距离,为目标机提供掩护区域,实现安全突防。

Aiming at the problem that the existing evaluation methods of radar detection performance without considering and combining the stealth performance and ability of electronic warfare,a method based on supportjamming of stealth aircraft was proposed.Radar detection coverage to stealth aircraft in the whole airspace was simulated by using smooth processing static RCS of stealth aircraft and radar distance formula.Then the maximum operation range and minimum detection range of radar were selected acting as jamming range of stealth aircraft,and the variation of radar detection coverage was compared and analyzed after setting jamming range of ordinary jammer.Support-jamming effectiveness was analyzed quantitatively by defining jamming suppression ratio.The simulation results show that support-jamming of stealth aircraft would have prominent jamming tactics,reduce radar detection range evidently,and provide covering area to finish safe penetration for target aircraft.
