【摘要】：為實(shí)現(xiàn)對(duì)空間目標(biāo)紅外輻射進(jìn)行定量測(cè)量,需要解決紅外輻射測(cè)量系統(tǒng)的標(biāo)定問題。針對(duì)常規(guī)標(biāo)定方法對(duì)大口徑紅外輻射測(cè)量系統(tǒng)標(biāo)定存在的不足,在對(duì)其測(cè)量原理分析的基礎(chǔ)上,提出了一種內(nèi)置黑體標(biāo)定與天文恒星標(biāo)定相結(jié)合的新方法。采用內(nèi)置黑體作為標(biāo)準(zhǔn)輻射源對(duì)匹配鏡組和探測(cè)器進(jìn)行標(biāo)定,采用恒星標(biāo)準(zhǔn)輻射源對(duì)大口徑主光學(xué)系統(tǒng)透過率進(jìn)行標(biāo)定,并推導(dǎo)出了紅外輻射測(cè)量系統(tǒng)整體的響應(yīng)關(guān)系。試驗(yàn)驗(yàn)證表明,該方法與傳統(tǒng)的全孔徑標(biāo)定方法相比,曲線斜率誤差在4%以內(nèi),具有操作簡(jiǎn)單易行、標(biāo)定系統(tǒng)的研制難度低、標(biāo)定效率高等優(yōu)點(diǎn)。
[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.
