| 摘 要： | 空间谱估计测向体制工程实现的暂时困难，影响了人们对其光明前景的认识。鉴此，文章提出了关于空间谱估计测向体制取得超过传统测向体制的精度、分辨力和对同频多信号同时测向的机理的物理解释和数学解释，以揭示这种新体制所具有的不可遏制的内在生命力。主要机理为，单点观察变为多点观察、样本域的扩张、参量估计更有效和变量方程的拓展。文章对几个实际系统进行了分析和评介。这些系统已经展示出空间谱估计测向体制所具有的超过传统体制的优异性能。

| Abstract: | Difficulty in making spatial spectrum estimate direction finder has been shading the bright future of the latter. The mechanism analysis to Super-performance of DF using spatial spectrum estimate is presented. The analysis consists of physical one and mathematic one. Several real systems are introduced and reviewed. Super-performance of the new DF method has been shown by the systems. |
