卫星激光反射器阵列结构决定有效反射面积分布,进而影响激光回波强度。在某些小型卫星应用中,地面台站只需对卫星局部天区过境观测,但激光反射器需数十平方厘米的有效反射面积,且对质量和尺寸有限制,需合理设计激光反射器阵列排布指向以满足大的有效反射面积应用需求。推导了不同指向角反射器有效反射面积计算模型,并以某一局部天区观测的低轨卫星激光反射器为例,给出了有效反射面积的仿真结果,并进行了实验室测试。结果表明,局部天区观测卫星激光反射器的有效反射面积设计与测试结果相符,为区域观测卫星激光反射器应用奠定了基础。
Satellite laser reflector array structure determines the effective reflection area distribution, thereby affecting the laser echo intensity. In some small satellite applications, the ground station only needs to observe the transit area of the satellite’s local sky area. However, the laser reflector needs dozens of square centimeters of effective reflection area, and its quality and size are limited. Therefore, the laser reflector array needs to be designed reasonably Arranged to point to meet the large effective reflection area application requirements. The calculation model of the effective reflection area of different azimuth angle reflectors is deduced. Taking the low-orbit satellite laser reflector observed in a certain area as an example, the simulation results of the effective reflection area are given and the laboratory tests are carried out. The results show that the design and test results of the effective reflection area of satellite laser reflectors in local area coincide with each other, which lays the foundation for the application of the laser observer in the area observation satellite.
