angular spreading造句

The innovations of this thesis are as the follows : 1 ) it is analyzed that the lower - order jacobi - anger expansion model for an incoherently distributed source has better accuracy performance than some other approximate source models such as space frequency model , two - point source model , and low - rank approximate model . using the parametric decoupling property of the ja - based model , a novel angular parameter estimator is proposed , which is very robust in case of large angular spreading
本文从这三个方面开展了空间分布源波达方向估计研究，创新点包括： 1 )分析了低阶jacobi - anger级数展开近似模型的误差性能；利用该近似模型的参数解耦特性，提出了一种新的波达方向估计器，在大角度扩展条件下，该估计器表现非常稳健。
