摘　　要：为解决红外目标隐身效果评估过程中辐射计视场响应不均匀对测量结果的影响,提出一种等立体角标定和测量的方法。采用同光路原理消除光学系统轴外像差造成的视场响应非均匀对测量结果的影响,实现红外隐身目标辐射强度等参数的标定和测量。以标准黑体为测量对象,采用本文提出的测量方法对其在(3~5)μm的积分辐射强度进行实验验证,结果表明其测量值与标准值相对误差小于2%,测量相对不确定度优于3.7%(k=2)。In order to solve the problem about the influence of non-uniform field-of-view（FOV）response of radiometer on the measurement results during the assessment of infrared target stealth effect,a method of calibration and measurement under the same solid angle was put forward.The influence of the FOV response non-uniformity on the measurement results caused by off-axis aberrations was eliminated by adopting the principle of the same optical path.The calibration and measurement of the IR target radiation intensity and other parameters was realized.Finally,we adopted standard blackbody as the measuring object,and the 3μm ～5μm integral radiation intensity was verified by using the proposed method.The result shows that the difference between the measured and standard values is less than2%,and the measurement uncertainty is better than 3.7%（k=2）.
