摘　　要：近年来,航天技术的蓬勃发展使得空间碎片日益增多,严重影响在轨航天器的安全运行,因此需要对空间碎片进行探测和清除。随着对空间碎片探测要求的不断提高,空间碎片探测系统逐渐向一体化和多功能化的方向发展。提出了一种测距成像通信一体化的光学系统,通过分析成像跟踪的最大探测距离以及测距通信的接收功率,优化选取一体化光学系统中的最佳参数。分析得到的最佳遮拦比在0.144~0.172范围内,次镜膜层透射率在0.3~0.6范围内,且最佳透射率为0.462。该研究为用于空间碎片探测的一体化系统的研究提供参考。In recent years, space debris is increasing with the development of space technology, and has a serious effect on the safety operation of on-orbit spacecraft. Therefore, it is urgent to detect and remove the space debris. With the increasing demand for space debris detection, the space debris detection system gradually develops to a integrated and multifunctional system. An integrated optical system of ranging, imaging and communication is proposed. The maximum detection range of imaging tracking and the received power of ranging communication are analyzed, and the optimum parameters of the integrated optical system are chosen. The results show that the best obscure ratio is in the range of 0. 144-0. 172, the transmittivity of secondary mirror film is in the range of 0.3-0.6, and the optimal transmittivity is 0. 462. This study provides a reference for the study on the integrated system used for space debris detection.
