摘要
对双反射镜圆锥扫描红外地平仪和楔镜圆锥扫描红外地平仪的工作原理及瞬时视场进行了比较,计算了两种类型红外地平仪的瞬时视场进出地球的扫描延时,分析了扫描延时对姿态角测量误差的影响。
Compared the working principle and the instantaneous field of view of double mirrors conical scanning infrared earth sensor and wedge lens conical scanning infrared earth sensor, the scanning delay of two types of infrared earth sensor＇s instantaneous field of view access to the Earth is calculated, analyzed the attitude angle measurement error caused by the scanning delay.
