对空间跟踪与监视系统预警探测单元的探测视场、成像像素规模、空间分辨力、光学增益等光学系统性能进行了逆向工程解算；基于目标与背景的短波红外辐射特性，对该预警探测单元的工作波段进行了定量分析，提出了其预警探测单元并非工作在传统预警卫星常用的低大气透过率波段(2.5~2.9μm)的新观点。计算结果表明，在强背景噪声条件下，预警探测单元采取高大气透过率波段(2~2.4μm)的选通滤波措施，可获得最优探测能力。

According to the open literature, the characteristics of optics system about the visual angle, pixel number,space resolution and optics plus of the early warning detecting of space tracking and surveillance system are computed conversely. Base on the shortwave infrared radiation characteristics of target and background, wave band of the early warning detecting is analyzed, and a new viewpoint that early warning detector don’t work in low atmosphere transmittance of wave band for traditional early warning satellite is proposed. The results show that, under the high noise background, early warning detection unit can obtain the best detecting capability by taking strobe filtering measures to the waveband of high atmospheric transmittance.
