  1. It contributes to the deeper comprehesion of these probability distributions, affords more detailed theoretical basis for further studying and simulating satellite mobile channels, ? theoretical analyses and discussions of the models which are often used in the study of the propagating characteristics of satallite mobile channels are given ; meantime, some discussions on the work of model simulations are also given, ? incorrect derivation of the equality between c. loo model and corazza model in some other papers is pointed out. via the conception of received power, we derivate that in the rural environments these two models really have the equal relationship by the way of theoretical derivation and simulatant fittings. therefore, it is able to use corazza model in studying the characteristics of satellite mobile channels in the rural environments and able to avoid the iterant work of modeling, in order to enhance the efficiency and accuracy of research work, ? detailed processes of simulating lutz model by using matlab6. 0 _ simulink4. 0 and the results of comparisions are given

    本文包含有以下的主要內容： ?對衛星移動通信通道傳播特性研究中常用的三個概率分佈給出了詳細的推導過程；以便對這幾個在衛星移動通信通道傳播特性的研究中常用的概率分佈函數有更深的理解，對進一步研究衛星移動通信通道傳播特性和對通道的建模提供了更為詳盡的理論基礎； ?對衛星移動通信通道傳播特性的研究中常用的通道模型進行了理論上的分析和討論，並對衛星移動通信通道建模的研究工作提出了一定的看法； ?指出了以前的文獻中關于c . loo模型和corazza模型的等同性的證明錯誤；並從接收信號功率的角度出發，通過理論推導及模擬曲線擬合重新證明了在鄉村環境下，這兩個模型的確是具有等同性的；從而在對鄉村環境下的衛星移動通信通道傳播特性進行研究時，可以只採用corazza模型來對實際的通道進行建模，這樣可以避免重復的建模工作並提高研究工作的效率和準確性； ?給出了lutz模型在matlab6 . 0 _ simulink4 . 0環境下的軟體模擬實現的詳細過程和整體模擬測試的對比結果，保證了該模型在硬體實現時的可靠性和可行性，從而可以將它們應用於指導模型的硬體模擬實現並可以降低硬體實現時的風險。

    對兩曲面求交問題，當曲面細化足夠小時，曲面求交可近似看成曲面與平面相交問題，引進了邊界點的概念，因此只要知道交線上的任意點，就可以將跨越許多曲面片的整條交線計算出來，所求出的交線或者跨越曲面的邊界，或者形成交線環；從初始點出發跟蹤求解整條交線的過程中，步長的選擇採用了通過曲面片曲率來約束的方法，用該方法求出的交點在不同曲面片上的分佈數目不與弦長成正比；該求交方法包含了各曲面片的邊界線與交線的交點的求解，可獲得邊界交點的坐標值及其參數值。
