4 、基於抗差估計理論，討論了航空重力測量系統誤差模型參數的抗差m估計方法與實現。 -
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
本文從這三個方面開展了空間分佈源波達方向估計研究，創新點包括： 1 ）分析了低階jacobi - anger級數展開近似模型的誤差性能；利用該近似模型的參數解耦特性，提出了一種新的波達方向估計器，在大角度擴展條件下，該估計器表現非常穩健。 -
