1) steerable
移动波束
1.
Benefitting from GRASP8 Student Edition,which provides a free,open antenna simulation module,an analytic tool specially for steerable antenna is developed by VC++ and MATLAB and produces good results in accordance with actual patterns.
针对偏馈形式的移动波束天线,分析了波束指向和双轴转角的换算关系,二次开发了反射面天线仿真计算软件GRASP8SE,最后对天线在波束扫描状态下的电性能进行了仿真计算,并和实测结果做了对比。

偏移波束
3) BDRM
波束位移
1.
In this paper,during building broadband acoustic model based on beam-displacement ray-mode theory(BDRM),fast arithmetic for approximate normal-mode calculation of broadband acoustic signals in shallow water with a thermocline is proposed based on an expansion of eigenvalues,eigenfunctions and modulus decay with respect to frequency.
本文在波束位移射线简正波(BDRM)理论基础上实现宽带声场建模,在宽带建模过程中利用频域展开方法对宽带信号的本征值、本征函数和衰减系数进行插值计算,减少繁琐的方程解算,提高了计算速度,缩短了计算时间。
