载体平台对天线辐射特性的影响不容忽视,但由于计算机物理内存的限制,使得某些电大平台天线辐射问题无法计算。针对上述问题,采用了利用硬盘代替内存的核外求解方法;为加快求解速度,提出了一种核外分块高斯消元方法。将数据按块集中读写,从而极大地缩短了对硬盘操作的时间。分别计算了金属圆柱平台天线和车载平台天线的辐射方向图。结果表明,本方法可快速求解电大平台天线辐射问题,求解时间与核内方法只相差5.9%,而且不损失计算精度。
The influence of the carrier platform on the radiation characteristics of the antenna can not be ignored, but due to the limitation of the physical memory of the computer, the radiation problem of certain electric platform antennas can not be calculated. In order to solve the above problems, an out-of-core solution using hard disk instead of memory is proposed. To speed up the solution, an extra-core block Gaussian elimination method is proposed. The data is read and written by block, which greatly shortens the operation time of the hard disk. The radiation patterns of the metal cylindrical platform antenna and the vehicle platform antenna are respectively calculated. The results show that this method can quickly solve the radiation problem of radiant platform antenna. The solution time is only 5.9% less than that in the nuclear method, and the calculation accuracy is not lost.
