摘　　要：新型红外地球模拟器作为线阵静态红外地平仪研制的保障条件之一,对其进行地面的检测和标定。为保证线阵静态地平仪的研制精度,需要地球模拟器为线阵静态红外地平仪提供高精度地平辐射的等效模拟信号,以检测线阵静态红外地平仪的性能,而地球模拟器的仿真精度取决于其光学系统,通过对地球模拟器二次光学系统进行设计,以及进行温度控制,其温度控制精度、姿态角仿真精度均能达到设计要求。新型地球模拟器姿态角实现0.1°仿真精度,保证了线阵静态红外地平仪像元分辨率的测试要求。Linear array static infrared horizon sensor is an essential satellite attitude control instrument, that provides horizon circle position signal by detecting the earth＇s infrared radiation energy. As one of the assuring conditions, new infrared earth simulator for linear array static infrared horizon sensor could achieve the ground testing and calibration. To ensure the space operating reliability of the linear array static infrared horizon sensor, the earth simulator provided the high quality scene simulation signals of the earth＇s infrared horizon radiation for linear array static infrared horizon sensor, the earth simulator＇s simulation accuracy depended on its optical system, the temperature control and attitude angle simulation accuracy could meet the design requirements by the earth simulator secondary optical system designing and temperature controlling. The attitude angle simulation accuracy of new-style earth simulator is 0.1~, which meets the test requirements of the static horizon-pixel resolution.
