摘要
建立了空间非自发光目标的数学模型,应用经典光学理论研究了目标亮度与目标尺寸、表面特性、观测角、观测距离之间的关系;并推导了探测能力与光学系统参数及曝光时间之间的关系;试验结果验证了模型和计算公式的正确性,可为空间目标探测光学系统的设计提供了设计参考.
In space targets,about 7% of them are manmade satellites; others are space relics of debris. Only rely on sun shining can these targets be detected because all of them do not illuminant themselves. They are so far from the sensor that can be considered as point targets. Mathematics model of unilluminant space target is set up. Based on classical optical theory the relationships between brightness and dimension and surface characteristic and view angle and distance are analyzed; and the relationships between detection ability of optical sensor and parameters of optics and exposal time are demonstrated based on energy conservation law. In the end the correctness of the model and formula are proved by test, so it can provide reference to optical system design used in space un-illuminant targets detection.
