摘要
针对导引头对多目标角度超分辨需求,提出了一种基于数字阵列雷达导引头的角度超分辨估计算法。对多重信号分类(MUSIC)算法空间谱的二次求导,搜索其负向谱峰,可获得较高的多目标角度分辨率和角估计精度,仿真验证了不同条件下方法的有效性和可行性。该算法复杂度较低,利于工程实现。
Aim to the requirement that the seekers need multiple target direction of arrival（DOA）superresolution,a method of super-resolution DOA estimation in the digital array radar seeker was proposed in this paper.By calculating the second differentiation for the multiple signal classification（MUSIC）spatial spectrum and seeking the negative peaks,the proposed estimation method could obtain high angle resolution and angle precision.The simulation results proved the effectiveness and feasibility of the method proposed under different conditions.The method had the low computational complexity and could be easily applied to engineering.
