摘　　要：空间目标可见光相机的探测能力主要与相机自身收集目标信号的能力、相机本身的背景噪声以及探测器组件的噪声水平有关。衡量空间目标可见光相机探测能力的主要技术指标是信噪比。在国内外相关资料比较缺乏的情况下,文章通过原理研究和理论推导,得到了空间目标可见光相机探测能力理论计算公式,并用实例进行了例证,表明该方法正确可取,为空间目标可见光相机设计时对探测能力的分析和预估提供了理论计算方法。The detect ability of space object visible camera is related to the target signals collection capabilities, camera background noise and focal plane array assembly noise. In general, the primary specification for expressing detect ability is SNR. A set of theory calculation formulae of detect ability are derived in the paper, and a simulation is conducted through an example according to the theory calculation formulae. For space object visible camera design, the theory methods of detect ability analysis and estimation is provided.
