地球轨道和月球表面超长波长干涉仪的仿真研究

Simulation of Ultra-Long Wavelength interferometer in the Earth orbit and on the lunar surface

Mo Zhang, Maohai Huang, Yihua Yan

摘要:

我们提出了在地球轨道和月球表面的干涉仪阵列的模拟,以指导设计和优化的天基超长波长任务,如中国的嫦娥计划。我们选择参数,并使用模拟数据进行模拟,以确定科学和工程参数的相互依赖性和约束。建立了月壤模型,对月面阵进行了仿真,仿真结果表明月壤会对月面阵的观测产生不良影响。我们估计数据传输的要求,计算灵敏度为两种情况下,并讨论了亮度温度灵敏度和角分辨率的地球轨道阵列的情况下之间的权衡。

英文摘要:

We present simulations for interferometer arrays in Earth orbit and on the lunar surface to guide the design and optimization of space-based Ultra-Long Wavelength missions, such as those of China's Chang'E program. We choose parameters and present simulations using simulated data to identify inter-dependencies and constraints on science and engineering parameters. A regolith model is created for the lunar surface array simulation, the results show that the lunar regolith will have an undesirable effect on the observation. We estimate data transmission requirement, calculate sensitivities for both cases, and discuss the trade-off between brightness temperature sensitivity and angular resolution for the Earth orbit array case.
