摘要
推导了自旋扫描方式成像的静止气象卫星通常情况下太阳脉冲延迟角β的公式,并对用线性近似公式计算β角带来的误差进行了分析,提出用β角的一阶时间导数为斜率的线性近似公式,还推导了卫星自旋轴相对地轴倾斜时的β角计算公式。
In the paper, methods for calculating angle β are discussed. The errors caused by using the simple linearly approximate formula are analyzed, and an effective linearly approximate formula which uses dβ/dt|t=t_0 as its slope is presented and analyzed. Considering the situation that the satellite axis is unparallel to the earth axis, the calculation formula for angle β is given.
