摘　　要：红外地球敏感器是卫星姿态测量的关键部件之一。在研制过程中,需要红外地球波信号源为其提供电激励信号,组成闭环测试系统,从而完成对红外地球敏感器的地面测试与标定。针对红外地球敏感器研制过程中逻辑功能验证、精度测试、可靠性环境寿命试验等需求,提出一种高精度的模拟式红外地球波算法。在对算法的精度、实时性等进行仿真分析的基础上,设计了一种红外电地球波模拟器的硬件实现方案,并研制了样机。试验结果表明,该算法及系统能够满足红外地球敏感器地面测试中的实时性和高精度需求。Infrared earth sensor is one of the key components in satellite attitude measurement.In order to accomplish the calibration and test of infrared earth sensor,a signal stimulating source is required to provide electric earth wave signals so that a closed-loop testing system can be constituted.According to the requirement of accuracy test,environment test and reliability test of infrared earth sensor,a new high accuracy infrared analog earth wave algorithm is proposed.The infrared earth wave simulator is developed based on the analysis and simulation of the algorithm accuracy.Test results show that the algorithm and test equipment can satisfy the high accuracy and real-time requirement.
