1·引言预计一个“天线罩一天线”组合之瞄准误差的问题,在实践上不能被精确地解决,既使可能存在这样的一个解,在研究一种设计方法方面,它也不会很有用。一种更有成效的方法是得到对瞄准误差产生的各种过程作定量了解,并由此对问题进行综合。在小误差时,可以证明:合成瞄准误差是各分量误差的代数和。对壁厚在半波长范围的天线罩,此法是可行的。 1. INTRODUCTION The problem of estimating the aiming error of a “radome-antenna combination” can not be solved in practice, and it would not be useful to study a design approach, even though one such solution might exist . A more effective method is to get a quantitative understanding of the various processes that result from aiming errors and to synthesize them. In the case of small errors, it can be shown that the synthetic aiming error is the algebraic sum of the component errors. This method is feasible for radomes with wall thicknesses in the half-wavelength range.
