多辐射源合成场对反辐射导弹的诱偏作用

Modeling of Electromagnetic-field-combined Profile of Multiple Radiation Sources as Well as Its Decoying Effect on ARM

本文在考虑方向图、极化方式的基础上确立了一种多辐射源合成场的仿真模型,获得了这种模型下多辐射源合成场及坡印亭矢量空间分布公式,并以雷达与诱饵合成场为例给出了多辐射源合成场的仿真思路、计算公式和模拟结果.数值计算表明,雷达和诱饵的典型布阵可以使多辐射源合成场坡印亭矢量反方向指向人为设置的陷阱区域,从而能够对反辐射导弹有效诱偏.

A theoretical model is proposed for analyzing and simulating the electromagnetic-field-combined profile of several radiation sources in this paper. The formulae of the electromagnetic-field-combined profile and Poynting Vector have been obtained under the consideration of field pattern and polarization. A typical application of several radiation sources, disturbing the tracking of Anti-radiation missile （ARM） with radar and decoys,has been simulated and simulation results show that ARM may be decoyed to a trapped area through the electromagnetic-field-combined profile if three decoys have been distributed near the radar in an appropriate way.
