Abstract
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.
