【摘要】：考慮標(biāo)準(zhǔn)紅外星定標(biāo)方法無法測定地基大口徑紅外光電系統(tǒng)像元級的輻射響應(yīng)度,進而導(dǎo)致對系統(tǒng)存在的非均勻性現(xiàn)象適應(yīng)能力差的問題,提出了基于標(biāo)準(zhǔn)紅外星與小口徑黑體的聯(lián)合輻射定標(biāo)方法。該方法以標(biāo)準(zhǔn)紅外星為外定標(biāo)參考源,測定全光路系統(tǒng)的輻射響應(yīng)度;以小口徑黑體為內(nèi)定標(biāo)參考源,測定半光路系統(tǒng)像元級的輻射響應(yīng)度;最后,結(jié)合內(nèi)、外定標(biāo)結(jié)果推算前端光學(xué)系統(tǒng)透過率,進而實現(xiàn)系統(tǒng)的全光路像元級輻射響應(yīng)度定標(biāo)。開展了自然星紅外輻射特性測量實驗,并與標(biāo)準(zhǔn)紅外星定標(biāo)方法進行了對比。結(jié)果顯示:提出方法獲得的目標(biāo)最大反演誤差為15.89%,而標(biāo)準(zhǔn)紅外星定標(biāo)方法在最理想情況下獲得的最大反演誤差為15.92%,表明提出方法的定標(biāo)精度高于標(biāo)準(zhǔn)紅外星定標(biāo)方法。另外,提出方法能夠測定全光路系統(tǒng)像元級的輻射響應(yīng)度,克服了系統(tǒng)響應(yīng)非均勻性的影響,進而提高了紅外探測器的焦平面利用率,彌補了標(biāo)準(zhǔn)紅外星定標(biāo)方法的應(yīng)用缺陷。
[Abstract]:Considering that the standard infrared star calibration method can not measure the radiative response of the pixel level of the large aperture infrared photoelectric system on the ground, which leads to the poor adaptability to the non-uniform phenomenon of the system. A combined radiometric calibration method based on standard infrared star and small aperture blackbody is proposed. Using the standard infrared star as the external calibration source, the radiation response of the all-optical path system is measured, and the radiation response of the half-optical system pixel level is determined with the small caliber black body as the internal calibration reference source, and the radiative response of the half-optical system is determined by using the standard infrared star as the external calibration source. Finally, based on the internal and external calibration results, the transmittance of the front-end optical system is calculated, and then the all-optical path pixel-level radiative response calibration of the system is realized. The infrared radiation characteristics of natural stars are measured and compared with the calibration methods of standard infrared stars. The results show that the maximum inversion error of the proposed method is 15.89%, while the maximum inversion error of the standard infrared star calibration method is 15.92% under the optimal conditions. It is shown that the calibration accuracy of the proposed method is higher than that of the standard infrared star calibration method. In addition, the method can measure the radiative response of all-optical system pixel level, overcome the influence of non-uniformity of system response, improve the utilization rate of focal plane of infrared detector, and make up for the application defect of standard infrared star calibration method.
