Study the impact of electromagnetic radiation on spacecraft with non sealed equipment bay
The transition from the sealed design of the equipment bay of the spacecraft inevitably leads to an increase in the strengths of the electric field from the transmitting antennas inside the equipment bay. To ensure the electromagnetic compatibility of the spacecraft and to correctly set the requirements for the susceptibility to the alternating electric field of on-board equipment, it is necessary to have data on the shielding efficiency provided by the equipment bay. In this article results of experimental studies to determine the interaction of electromagnetic radiation with non sealed equipment bay of spacecraft in frequency range 200-18000 MHz are considered. The description of methods of testing and processing of results is given. As a result of the work, basic data were obtained on the effectiveness of screening of the equipment bay, the propagation of field around and inside the equipment bay, and the effectiveness of measures to ensure the absence of radio leakage of the equipment bay was confirmed.
