4.1 引言可以设想,由于AROD系统的跟踪信号穿过大气层进行传播,故会引起测距误差。必须测出这些误差量的范围,以便确定整个AROD系统的测距精度。除需确定这些误着有多大以外,还需对进入实际测距中的传播误差进行粗略的修正。本文的目的在于确定这些误差的近似范围,并研究这种粗略测距修正方法的优点。
4.1 Introduction It is conceivable that since the tracking signal of the AROD system propagates through the atmosphere, it will cause ranging error. The range of these errors must be measured in order to determine the accuracy of ranging of the entire AROD system. In addition to determining how much of these mispricings, there is a need to make a rough correction to the propagation error that enters the actual range. The purpose of this paper is to determine the approximate range of these errors and to investigate the advantages of this rough ranging correction method.
