文中讨论了飞机热图像动态范围和量化问题。发现：飞机热图动态范围很大，而目前所用8bits量化器无法与探测器动态范围相匹配，因而引起热图质呈下降，降低了辐射强度计算精度。因此提高量化级数，采用非均匀量化，可以明显改善热图质量，显著提高辐射强度计算精度。计算机仿真结果证实了这一观点的正确性。
The paper discusses the dynamic range and quantification of aircraft thermal images. It is found that the dynamic range of the aircraft heat map is very large. However, the 8bits quantizer currently used can not match the dynamic range of the detector, thus causing a decrease in the heat map and reducing the calculation accuracy of the radiation intensity. Therefore, improving the quantization level, using non-uniform quantization, can significantly improve the quality of heat map, significantly improve the calculation accuracy of radiation intensity. Computer simulation results confirm the correctness of this view.
