摘要:

针对飞机躲避单脉冲导引头攻击的需求,提出一种基于级联拖曳式散射调控反射器的无源角闪烁干扰方法。通过电控调制,反射器可以在透射态和反射态之间快速切换,从而产生复杂的角闪烁效应。首先通过构建广义拉格朗日方程分析反射器的运动学特性,然后建立角闪烁干扰的数学模型,最后对转向机动条件下电控反射器对单脉冲导引头的角度干扰效果进行分析。结果表明,利用伪随机信号对反射器进行雷达散射截面调制,可以显著增大导引头的测角误差,误差可达到1.8°以上。所提方法能够有效对抗单脉冲雷达的角度跟踪,可为高价值机动目标提供突防手段。

Abstract:

A passive angular blinking jamming method based on cascaded towed scattering-controlled reflector is proposed to meet the demand of aircraft evading single pulse guidance head attacks. The reflector can be quickly switched between the reflection mode and the penetration mode through electronically controlled modulation, thereby producing a complex angular blinking effect. Firstly, motion characteristics of reflector are analyzed through the Lagrange equation. Secondly, the mathematical model of the blinking jamming is established. Finally, the angle jamming effects of electrically controlled reflector on the single pulse seeker with steering maneuvering conditions is analyzed. The results show that using pseudo-random signals to modulate the radar cross section of the reflector can significantly increase the angle measurement error of the guidance head, with an error of over 1.8°. This method proves effective in countering the angular tracking capability of the monopulse radar, showing potential to serve as a penetration means for high-value maneuvering targets.
