Problems solved by technology

[0003] The electronic calibration test of the space electric field detector needs to be carried out on the ground to verify the performance of the indicators. Since the main detection object of the space electric field detector is the electric field, the ground calibration test will inevitably be interfered by the artificial electromagnetic environment, which is not conducive to the electronics of the space electric field detector itself.

Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0017] The design principle of the present invention: the space electric field detector needs to carry out the electronic calibration test to verify the index performance on the ground. Since the main detection object of the space electric field detector is the electric field, the ground calibration test will inevitably be interfered by the artificial electromagnetic environment, which is not conducive to the space electric field. Calibration and performance assessment of the electronic parameters of the detector itself. The Faraday cage is a widely used electromagnetic shielding device. It is an equipotential body in the space electromagnetic wave environment. The potential difference inside the cavity is zero, that is, the electric field is zero, which is very beneficial for the space electric field detector to eliminate external electromagnetic interfere...

Description

technical field [0001] The invention belongs to the technical field of space environment detection, and relates to a test system and method for electronic calibration of a space electric field detector. Background technique [0002] The space electric field detector, a satellite payload product used in space environment detection scientific activities, is composed of a signal processing unit, a reel-type extension rod, a sensor and other components. The barrel extension rod is transmitted to the signal processing unit for signal combination and processing, so as to obtain the field strength of the space electric field. [0003] The electronic calibration test of the space electric field detector needs to be carried out on the ground to verify the performance of the indicators. Since the main detection object of the space electric field detector is the electric field, the ground calibration test will inevitably be interfered by the artificial electromagnetic environment, whic...
