本文推导了红外分光计串音误差的解析表达式;提出了双积分处理方法,并进行串音误差计算,其结果比美国VTPR提出的箝位积分方法,有更好的性能。为计算信噪比,本文还提出一种计算时分网络输出噪声功率谱的方法。
In this paper, the analytical expression of the crosstalk error of infrared spectrometer is deduced. The double integration method is proposed and the crosstalk error is calculated. The result is better than the clamp integral method proposed by the American VTPR. In order to calculate the signal-to-noise ratio, this paper also proposes a method of calculating the output noise power spectrum of the time-division network.
