摘要

在本文中，我们考虑了2.x型和3.x型地外冯-诺依曼探测器，并研究了它们在世界上最大的单碟形射电望远镜——五百米口径球面射电望远镜（FAST）上的可探测性问题。为此，我们估计了无线电频谱参数，并在FAST技术特征的背景下分析了获得的结果。结果表明，FAST可以高精度地探测到银河系和河外的自复制探测器。

Can the China's fast telescope detect extraterrestrial von-Neumann probes?

In the present paper we consider the Type-2.x and Type-3.x extraterrestrial von- Neumann probes and study the problem of their detectability by the world's largest single-dish radio telescope: the Five-hundred-meter Aperture Spherical Radio Telescope (FAST). For this purpose we estimate the radio spectral parameters and analyse the obtained results in the context of technical characteristics of FAST. As a result, it is shown that FAST can detect both the galactic and extragalactic self-replicating probes with high precision.
