While carrying out the scheme , at first , the basic theory of antenna , array antenna and electromagnetic absorption , the performance parameter of antenna and parabolic antenna are deeply researched . in conformity , the characteristic and calculation of aperture field and near - to - far - field transformation for radiation pattern are detailed analyzed . second , the factors such as , the amount of the antenna elements , mutual coupling between each element , ground and the buildings on earth ' s surface , which affect the performance of array antennas ’ resultant field are stressed discussed 在系统实现过程中,课题首先从天线、阵列天线,以及电磁场计算方法的基本理论着手,分析了天线与抛物面天线的各项性能参数,以及天线的口面场和近-远区辐射场的特点和计算;进而,更加深入的讨论和研究影响天线阵列合成场强的各项因素,包括系统所使用的天线单元个数对阵列合成场的影响、天线单元之间由于互耦造成的影响、传播过程中地面和/或地面建筑物的影响等。
