Before using phase - only algorithm to achieve nulling, estimations of the number of interferential sources and the doa of interferential signals are needed. so, the spatial spectrum estimation basd on the maximum likelihood method ( capon method ) and music algorithm used for detecting the number of interferential sources and the doa of interferential signals are discussed in the second chapter
在採用phase - only演算法進行波束置零之前,需要估計干擾源的方向和個數,因此本文還在第二章介紹了發射數字波束形成中用於測定干擾源個數和方向的空間譜估計法? capon演算法和music演算法的測向原理,並分析了它們的性能和優缺點。 -
Since the effects of turbulent atmosphere is prominent, this thesis concentrates on the effects of the turbulent atmosphere on the laser beam propagation in the atmosphere. the atmosphere refractive index model, especially refractive index fluctuation, power spectrum, phase spatial structure constant are introduced in the following and the specific structure function is achieved
根據大氣折射率模型,以及折射率起伏功率譜密度和相位空間結構常數,得到具體的結構函數;通過長程情況下的馬爾科夫近似,得到了互相關函數,對數振幅和相位協方差函數。
