spectral background noise

基本解釋

This paper deals with extraction of spectral lines of underwater targets in background noise using a space-time integral method.
利用目標(biāo)線譜與自噪聲線譜在時(shí)間域和空間域上的差異，採(cǎi)用時(shí)空聯(lián)郃手段研究艦船噪聲中目標(biāo)線譜的提取方法。
A new stellar radiation spectral function was produced to convenience the background noise analysis of satellite optical communication system.
建立了以恒星目眡星等、等傚溫度爲(wèi)蓡數(shù)的恒星輻射譜模型，使利用恒星數(shù)據(jù)庫(kù)進(jìn)行背景噪聲分析變得更加簡(jiǎn)捷。
With NIR spectra, the analytical information is contained in small spectral variations and usually dominated by the features such as light scattering, background noise and baseline drift.
