Omnidirectional amplitude comparison monopulse direction finding system deception method based on frequency control array

The invention discloses a method for positioning deception of an omnidirectional amplitude comparison monopulse direction finding system based on a frequency control array, the method is different from a phased array by controlling beam pointing through a phase difference between array elements, and a frequency control array (FDA) radar can realize beam control with higher degree of freedom through a mode of introducing a frequency difference between the array elements. In an energy domain, space wave beam main lobe energy is bent due to the interference effect of field intensity, a virtual radiation source is formed, so that angle deception is formed on nABD direction finding of a reconnaissance receiver. Experiments show that by the adoption of the deception method, the detection precision of our radar can be improved, and the deception effect on an enemy jammer is enhanced. 本发明公开了一种基于频控阵对全向比幅单脉冲测向系统定位欺骗的方法，与相控阵通过阵元之间的相差控制波束指向不同，频控阵(frequencydiversearray,FDA)雷达通过在阵元间引入频差的方式可以实现更高自由度的波束控制。在能量域上即为空间波束主瓣能量由于场强
