摘　　要：为了满足月球敏感器和导航敏感器对月球目标的观测需要,设计了大口径高辐亮度月球模拟器,其有效辐照面积为Φ2 000mm.利用照明分析软件LightTools,通过建模与追迹方法对模拟器的月相、辐亮度和均匀度进行设计、仿真和分析.设计月相目标与月球亮度控制系统,对14种典型月相及其辐亮度进行实时控制,提出LED灯阵的辐亮度修正方法提高系统均匀度.测试结果表明:经过修正后,模拟器的辐亮度均匀度优于15.7%.该模拟器可作为月球观测目标供敏感器识别.In order to meet the requirements of observations of the moon as its target by navigation sensors and rendezvous and docking sensor, the moon simulator with large diameter and high irradiation uniformity was designed, the effective irradiation area is cP2 000 ram. Using LightTools software, the phases, radiance and uniformity of the moon simulator were designed, simulated and analyzed by modeling and tracing method. The phases of the moon and radiance control system was designed to control the 14 typical phases and radiance of the moon in real time. The radiance correction method of the LED array was put forward to improve the uniformity of the simulator. The test results show that the irradiation uniformity of the simulator is better than 15. 7o/6 after correction. It indicated that the simulator can be used as the target for sensor identification.
