星载激光反射器的有效反射面积直接影响卫星激光测距的回波强度,反射器阵列的形状决定了有效反射面积的分布.推导了星载不同倾角的角反射器在不同天区的有效反射面积的计算公式,并以神舟四号轨道舱的类圆台形的激光反射器阵列为例,给出了有效反射面积分布的数值计算结果.
The effective reflection area of spaceborne laser reflector directly affects the echo intensity of satellite laser ranging, and the shape of reflector array determines the distribution of effective reflection area.It is deduced that the effective reflection of spaceborne reflectors with different inclinations in different sky regions Area calculation formula and taking the circular truncated laser reflector array of Shenzhou IV orbiter as an example, the numerical calculation results of the effective reflection area distribution are given.
