论文摘要

星际通信网络中的数据速率由于恒星之间的距离较远而遭受平方法反向法。为了达到高(GBITS/s)数据速率,需要大量孔径和高功率的某种组合。另外,与直接路径相比,恒星的重力镜头可以通过恒星的重力范围浓缩信号,以产生$ 10^{9} $的订单。重力晶状体物理学对接收器和光圈的大小和位置施加了一组约束。这些特征包括最小和最大接收器尺寸,最大发射器尺寸以及中心的接收器距离。接收器和发射器的最佳尺寸是订单计。如此小的设备允许捕获光束中的主叶,同时避免了会影响较大孔的时间涂抹。这些属性和其他属性可用于描述透镜通信网络的最可能参数,并确定在HeliePentric参考框架中的通信节点的确切位置。

Data rates in an interstellar communication network suffer from the inverse square law due to the vast distances between the stars. To achieve high (Gbits/s) data rates, some combination of large apertures and high power is required. Alternatively, signals can be focused by the gravitational lenses of stars to yield gains of order $10^{9}$, compared to the direct path. Gravitational lens physics imposes a set of constraints on the sizes and locations of receivers and apertures. These characteristics include the minimum and maximum receiver size, the maximum transmitter size, and the heliocentric receiver distance. Optimal sizes of receivers and transmitters are of order meters. Such small devices allow for the capture of the main lobe in the beam while avoiding the temporal smearing which affects larger apertures. These and other properties can be used to describe the most likely parameters of a lensed communication network, and to determine exact position of communication nodes in the heliocentric reference frame.
