一种对反辐射导弹多源诱偏干扰的建模方法

Modeling method for multiple-source decoy jamming to the ARM

针对反辐射导弹(ARM)传统有源诱偏理论的不足,从单脉冲雷达跟踪合成波阵面法线方向的理论出发,对多个辐射源的诱偏公式在三维空间中作了推导,对多目标影响建立了较通用的干扰模型并分析得到该模型具有当只有一个干扰源时,诱偏方位角偏差跟目标干扰源方位角之差有关的特点,同时诱偏仰角偏差也有类似的特点。仿真了其对数据的影响,为算法的设计和测试提供了依据。

To overcome the shortcomings of the traditional active decoying theory controntmg an ARM （Anti-Radiation Missile）, the monopulse angle is utilized tracking principles to deduce in the Cartesian coordinate system the bias angle formulas due to multiple sources. A common jamming model is then established and some of its characteristics are analysed. Finally, the effect of bias angles generated by the model is simulated, which provides the basis for designing and testing the algorithms in the ARM seeker.
