功率計誤差對六端口反射計精度影響的蒙特卡洛計算機(jī)模擬
MONTE CARLO SIMULATION ANALYSIS OF EFFECT OF POWERMETER ERRORS ON MEASURING ACCURACY OF SIX-PORT REFLECTOR
-
摘要: 功率計檢測誤差對六端口反射計的測量精度影響是非常大的。對于一個實際的反射計,由于整個系統(tǒng)比較復(fù)雜,用常規(guī)方法很難估算出功率計檢測誤差對反射計的測量精度的影響。本文引用了一種概率統(tǒng)計方法蒙特卡洛(Monte Carlo)法對六端口反射計的測量精度進(jìn)行數(shù)值計算。并且用一個X波段的六端口反射計作為例子,給出了計算結(jié)果與直方圖。用這種方法可以為六端口反射計的合理設(shè)計提供依據(jù)。

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. -
