功率计误差对六端口反射计精度影响的蒙特卡洛计算机模拟
MONTE CARLO SIMULATION ANALYSIS OF EFFECT OF POWERMETER ERRORS ON MEASURING ACCURACY OF SIX-PORT REFLECTOR
-
摘要: 功率计检测误差对六端口反射计的测量精度影响是非常大的。对于一个实际的反射计,由于整个系统比较复杂,用常规方法很难估算出功率计检测误差对反射计的测量精度的影响。本文引用了一种概率统计方法蒙特卡洛(Monte Carlo)法对六端口反射计的测量精度进行数值计算。并且用一个X波段的六端口反射计作为例子,给出了计算结果与直方图。用这种方法可以为六端口反射计的合理设计提供依据。

Abstract: It is important that the powermeter errors will exert a tremendous influence on the measuring accuracy of six-port reflector. To estimate this influence is very difficult. In this paper, Monte Carlo simulation analysis is used. As a practical example of X band six-port reflector, it gives a set of computing results and diagrams. With this method it will provide scientific basis for designing six-port reflectors. -
