(Ⅰ)引言本文的企图是用工程上能允许的近似程度以比较简捷的方法解决一类天线,如弹体,卫星,飞船,飞机等一类飞行体上天线的计算问题。事实上,目前大致有四种解决这类天线问题的方法,这就是解析法,矩量法,几何光学绕射理论与物理光学绕射理论,其中最早的是利用经典电磁场理论根据边值问题得出精确解的解析法,然而,用这类方法往往只能解决形状简单的一类天线,即使如此,为了得到一个工程上可以计算的解析式,常常要花很大力气而得到的式子仍然是很冗长的,自从近年来出现了高速、大容量的计算机以来,提出了一种与计算机结合解决天线电磁场计算的所谓矩量法,原则上,利用这种方法,几乎任意形状与结构的天线结合积分方程计算式都可以得到满意的准确度,这是用电磁场理论解决天线问题的 (Ⅰ) INTRODUCTION The purpose of this paper is to solve the problem of the calculation of the antenna of a class of antennas such as missile, satellite, spacecraft, aircraft and so on by a relatively simple and feasible method. In fact, there are roughly four ways to solve this kind of antenna problem at present, which is the analytic method, the moment method, the geometrical optical diffraction theory and the physical optical diffraction theory. The earliest one is using the classical electromagnetic field theory according to the boundary value problem However, using this type of method often only solves an antenna of a simple shape, even though, in order to get an analytically computationally computable solution, it is often very hard to get the formula Is quite lengthy. Since the emergence of high-speed, high-capacity computers in recent years, a so-called method of moments that solves the electromagnetic field calculations of antennas has been proposed. In principle, an antenna of almost any shape and structure Combined with the integral equation equation can be satisfied with the accuracy, which is the electromagnetic field theory to solve the antenna problem
