预警机用两点源诱偏对抗反辐射导弹研究

Early warning aircraft applying two radiation sources decoy system against ARM

从空间分辨条件和反辐射导弹(ARM)几何运动的分析出发,推导出ARM以任意角攻击预警机时,用附加辐射源和预警机共同组成的两点源,在运动中能够安全诱偏ARM的数学模型,并计算分析了ARM分辨角、攻击角和ARM运动速度等因素对诱偏效果的影响,确定了假定条件下的最佳两点源距离,给出了两点源诱偏效果图,并就如何在实际中构建两点源提出了几点想法。

Based on space resolution condition and the ARM＇s geometry movement analysis, a mathematical model of two radiation sources decoy system composed of additive radiation source and early warning aircraft is deduced when ARM attacks early warning aircraft from any direction. The two radiation sources decoy system can safely cajole ARM. The influence of some elements are calculated and analyzed such as ARM＇s resolution angle, attack angle and velocity on cajolery effect. The optimal distance between two radiation sources under the assumed condition is ascertained. The effect figures of two radiation sources decoy system are given. Finally several ideals about how to compose two radiation sources decoy system in practice are put forward.
