Analyzing the capability of a radio telescope in a bistatic space debris observation system

摘要

A bistatic space debris observation system using a radio telescope as the receiving part is introduced.The detection capability of the system at different working frequencies is analyzed based on real instruments.The detection range of targets with a fixed radar cross section and the detection ability of small space debris at a fixed range are discussed.The simulations of this particular observation system at different transmitting powers are also implemented and the detection capability is discussed.The simulated results approximately match the actual experiments.The analysis in this paper provides a theoretical basis for developing a space debris observation system that can be built in China.
