【摘要】：為實現(xiàn)對空間目標紅外輻射進行定量測量,需要解決紅外輻射測量系統(tǒng)的標定問題。針對常規(guī)標定方法對大口徑紅外輻射測量系統(tǒng)標定存在的不足,在對其測量原理分析的基礎上,提出了一種內(nèi)置黑體標定與天文恒星標定相結(jié)合的新方法。采用內(nèi)置黑體作為標準輻射源對匹配鏡組和探測器進行標定,采用恒星標準輻射源對大口徑主光學系統(tǒng)透過率進行標定,并推導出了紅外輻射測量系統(tǒng)整體的響應關系。試驗驗證表明,該方法與傳統(tǒng)的全孔徑標定方法相比,曲線斜率誤差在4%以內(nèi),具有操作簡單易行、標定系統(tǒng)的研制難度低、標定效率高等優(yōu)點。
[Abstract]:In order to realize the quantitative measurement of infrared radiation of space target, the calibration problem of infrared radiation measurement system should be solved. In view of the shortcomings of the conventional calibration method in the calibration of large aperture infrared radiation measurement system, a new method combining blackbody calibration with astronomical star calibration is proposed based on the analysis of its measurement principle. The matching mirror set and detector are calibrated by using built-in blackbody as standard radiation source, and the transmittance of large aperture main optical system is calibrated by star standard radiation source, and the overall response relationship of infrared radiation measurement system is deduced. The experimental results show that the curve slope error is less than 4% compared with the traditional full-aperture calibration method, which has the advantages of simple operation, low difficulty in the development of calibration system and high calibration efficiency.
