A set of indexes for evaluating the partner of alliance is given. considering some indexes are hard to precision estimate, and analyzes some factors affecting the weights of attributes such as valuator ' s attitude towards indexes, importance of indexes in decision - making and reliability of estimate, it put forward a mass statistics approach on evaluating the partner of alliance and determining the weights of attributes
建立了合作夥伴評價指標體系，考慮到一些指標很難給出準確的評價值，以及評價者對指標的重視程度、指標在決策中的作用、指標評價值的置信度等因素對評價結果的影響，提出了確定評價指標值以及指標權重的一種集值統計方法。 -
Space spectrum estimation technology has a comprehensive perspective in the military and civilian applications, the estimation method based on higher - order statistics has better performance than that based on covariance. firstly, the thesis introduces the definitions and the attributes of the higher - order statistics
空間譜估計技術在軍用和民用方面都有著廣泛的應用情景，將高階統計量應用於空間譜估計，所得到的性能要好於基於協方差的空間譜估計。 -
First, the thesis introduces the definitions and the attributes of the higher - order statistics. it is insensitive to additive gaussian noise ( white or colored ), which is what we base on to doa problems. then two doa estimation algorithms based on higher - order statistics are presented, one is that forming cumulant matrix pencil used in esprit to estimate doa problems, the other is spectrum estimation method for doa estimation based on the eigenstructure analysis of the fourth - order cumulant, and comparing the effects of the estimation to conventional covariance - based doa algorithms "
論文首先對高階統計量的定義和性質作了介紹，特別指出了高階統計量對加性高斯噪聲（白色或有色）不敏感，這是我們利用它進行波達方向估計的理論依據，然後文中提出了兩種基於高階統計量的波達方向估計方法，一種是利用子空間旋轉不變技術構造四階累積量矩陣進行估計的方法，另一種是基於四階累積量陣特徵分解的空間譜估計測向方法，並將它們的估計效果與傳統協方差方法的效果進行比較。
