The localization of electromagnetic radiation leakage through cabin gaps is a critical and challenging aspect of electromagnetic compatibility design for spacecraft. This paper proposes a localization method based on synthetic aperture interferometric passive radiometry imaging. Electromagnetic radiation signals are measured at a certain distance from the spacecraft surface to form visibility samp...Show More
A K/Ka band dual band high gain horn antenna with shaped beam for HEO satellite has been developed for K/Ka band TT&C. The horn geometry uses both horizontal and vertical corrugations liner control profile with dual-depth vertical corrugations. The geometry of the horn is optimized to have maximum Edge of Coverage (EoC) within ±16° at all frequencies of interest. The measured results show that the...Show More
Aiming at the higher electromagnetic compatibility control requirements of GEO SAR satellite, this paper studies the analysis and verification technology of the electromagnetic radiation influence produced by the electronic equipment on SAR payload during the development of equipment and subsystems. A hierarchical electromagnetic compatibility analysis method is proposed to reduce the difficulty o...Show More
In order to solve the problem that the satellite with large reflector antenna cannot directly verify the electromagnetic compatibility between the antenna and the satellite, a satellite system-level semi-physical verification technology for electromagnetic compatibility is studied. The electromagnetic compatibility analysis between the large antenna and the satellite is carried out by the model hi...Show More
This paper gives an overview on system architecture and function of electromagnetic interference on-site detection system. A special RF filter bank was designed to protect the system, and radio monitoring technology is used to locate the source of the on-site electromagnetic interference, and help improve the safety features of satellite system more actively.Show More
The electric propulsion system has been widely used in geostationary satellites for the special advantages. The localized plasma flow generated by the ion thrusters has to be evaluated, which could impact the communication electromagnetic waves. A test method about amplitude attenuation and time delay is researched. The influence is evaluated by comparing the amplitudes and phases of S21 parameter...Show More
Electromagnetic interference (EMI) filters are treated much as the effective equipments for controlling EMI. However, traditional EMI filter design methods are difficult, because the measurements of impedances are not easy due to the existences of parasitic parameters. In this paper, EMI filters are modeled by scattering parameters(S-parameter.) The paper also gives EMI digital filter design metho...Show More
