This paper establish the mathematics formula of radiometric calibration of infrared staring imaging systems by an advanced weighting function based on the linearity response of infrared focal plane arrays sensor of infrared camera , and establish the mathematics formula of non - linearity based on the fact that the response of the irfpa is non - linearity 本文以紅外相機為例,在紅外焦平面探測器輻射線性響應的基礎上,采用一種先進的加權(quán)函數(shù)方法,推導出了紅外凝視成像系統(tǒng)輻射定標的數(shù)學表達式,同時在紅外焦平面陣列探測器輻射響應非線性的實際情況,推導了非線性的數(shù)學表達式。
