Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0034] In view of the fact that the existing electromagnetic compatibility test system cannot meet the high-altitude electric field radiation sensitivity test, an automatic test system with high-altitude electric field radiation sensitivity test is designed, which can meet the electric field sensitivity test of large-scale test objects such as launch vehicles within a height of 18m Require.

[0035] The main function of the high-altitude electric field sensitivity automatic test system is to simulate the electric field environment in the 1-18GHz frequency band, apply it around the large-scale test piece through the transmitting antenna, and generate an electric field strength of 20-200V / m within the height range of 3-18m. Test whether the product works normally under the condition of radiated electromagnetic interference.

Abstract

An automatic test system for high-altitude electric field radiation sensitiveness is disclosed and relates to the technical field of electromagnetic compatibility testing. The system comprises a large-sized detected member, an emission antenna system, a large power signal simulation system, a high-altitude upgrading platform, a field intensity monitor, an electric field probe and a control computer, wherein the control computer is used for sending control instructions to the large power signal simulation system via a signal interface board, the large power signal simulation system is used for generating small power microwave signals and amplifying the same, large power microwave signals are generated and transmitted to the emission antenna system, the emission antenna system is used for subjecting the coupled large power microwave signals to radiated emission into space, high field intensity electromagnetic wave signals are generated in space, the electric field probe is used for monitoring the high field intensity electromagnetic wave signals generated by the emission antenna system in space in real time, and monitoring results are sent to the control computer via the field intensity detector. The system disclosed in the invention can satisfy electric field sensitivity testing requirements for the large-sized measured member which is less than 18 m in height such as a carrier rocket and the like.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility testing, in particular to an automatic testing system for high-altitude electric field radiation sensitivity. Background technique [0002] The electric field sensitivity test is part of the electromagnetic compatibility test project. The current configuration of the electric field radiation emission test system refers to the RS103 item in GJB152A-1997 "Electromagnetic Radiation Emission and Sensitivity Measurement of Military Equipment and Subsystems". The configuration boundary of this test is A test table with a height of 0.9m above the ground, on which the device under test is placed. [0003] Disadvantages of this system: For a large system under test, such as a launch vehicle, the test height is as high as 18m, and the electric field sensor cannot be installed on the test part, the above-mentioned system under test cannot measure the applied electric field, and cannot m...
