Detection Of Hypersonic Targets In Space And Near Space By A Constellation Of Space Satellites

Currently, most of the detection methods for hypersonic moving targets in space and near space at home and abroad are based on space-based detection systems and ground-based detection systems, etc. for the detection of hypersonic moving targets. The space-based detection system consists mainly of space-based infra-red and space-based radar detection systems, which capture and track and intercept the flight and climb segments of targets via medium and high orbiting satellites. Ground-based detection systems are mainly used to detect airborne targets by means of long-range early warning phased array radars, ground-based multifunctional radars, gaze radars and electromagnetic fences in conjunction with ground-based infrared detection systems. Instead, we use the all-weather, real-time global coverage of satellite signals as a source of radiation to detect hypersonic targets in space and near space. Calculating the power loss of the satellite transmitting electromagnetic wave signals and subsequently receiving the return signals of its detection of space and near-space targets, based on the transmitting and receiving power of the satellite transmitting and receiving antennas, amplification, electromagnetic wave frequency and the propagation distance from the satellite to space and near-space moving targets, to obtain the minimum power value required to ensure that a single satellite can properly transmit and receive its detection of electromagnetic wave signals of space and near-space targets and their return signals. The satellite ephemeris and other data parameters of the world’s currently launched satellites in low, medium and high orbits, as well as satellites in synchronous orbits, were obtained and combined with the satellite simulation software STK to build a simulation model describing the distribution and operation of the space satellite constellation. Effective detection of hypersonic targets is achieved through computational analysis of their coverage by a constellation of space satellites.
