基于空间分离点的非相参有源诱偏技术

Techniques of Non-coherent Active Decoy Based on Space Separation Point

随着现代电子对抗技术的迅速发展,对抗反辐射导弹(ARM)的有源诱偏技术关注度不断提高,利用有源诱饵抗ARM是一种行之有效的方法。文中推导了非相参有源诱偏抗ARM的数学模型公式,根据ARM雷达导引头到达空间分离点前后提出了有源诱偏模型,并进一步对非相参两点源、三点源、四点源诱偏在不考虑空间分离点和考虑空间分离点两种情况下的诱偏效果进行了仿真与分析。结果表明:考虑空间分离点时,诱偏效果更好,而且更贴近实际。

With the rapid development of modem electronic countermeasure technology, more and more attention is being focused on the active decoy technology for anti-radiation missile（ARM）. It is an effective method to use active decoy against ARM. In this paper, the mathematical model formula of non-coherent active decoy confront ARM is derived. According to the ARM radar seeker before and after the arrival of the space separation point, an active decoy model is proposed. And the decoy effect on the non-co-herent two point source, three point source, four point source decoying in considering space separation point and not under the two conditions are simulated and analyzed. The results show that when the space separation point is considered, the effect is not only better, but also more close to the reality.
