| 摘 要： | 探测距离是衡量空间目标天基可见光相机探测、识别能力的一项重要指标.本文从辐射度学和光度学出发,通过对目标光度特性、天空背景特性、CCD噪声特性进行计算分析,建立了信噪比模型,信噪比模型是关于探测距离和成像像元个数的隐式.根据Johnson法则中成像像元个数与探测效果的对应关系,得出探测信噪比、探测距离与探测效果之间的关...

| Abstract: | The range of detection is one important specification for expressing the ability of detection and recognition of space-based optical camera.According to the principles of photometry and radiometry,through analysis of the target luminosity characteristics,the sky background characteristics and the CCD SNR characteristics,SNR model was established.According to the connection between the pixel numbers and the detection result,the relationship among SNR,detection distance and detection result was obtained.At la... |
