本文应用概率链图形法较为直观和方便地计算了窄滑窗计数型检测器的方位角测量误差,并在给定参数下给出了计算公式和结果,同时还分析了终了准则对测角方差的影响。为了便于比较,还计算了相应参数下普通滑窗式检测器的测角误差。结果表明,一次不起始就判终了的窄滑窗计数型检测器的测角精度比普通滑窗式要高0.4个方位刻度左右;而两次连续不起始才判终了的窄滑窗计数型检测器的测角精度却与普通滑窗式大体相同。
In this paper, we use the probability chain graph method to calculate the azimuth measurement error of the narrow-sliding window counting detector intuitively and conveniently, and give the calculation formulas and results under the given parameters. At the same time, Impact. For ease of comparison, the angular error of the ordinary sliding window type detector under the corresponding parameters is also calculated. The results show that the accuracy of angle measurement of the narrow-window counting detector, which is not started once, is about 0.4 azimuths higher than that of the ordinary sliding window. However, two consecutive narrow-window counting Type detector angle accuracy is generally the same with the ordinary sliding window.
