The system comprises a control and data processing module, a high and strong radiation field simulation signal source, a low frequency field strong radiation array, and a multi-channel receiving device. The high and strong radiation field simulation signal source is connected with the control and data processing module through a circuit and used for outputting high and strong radiation field simulation signals. The low frequency field strong radiation array is respectively connected with the control and data processing module and the high and strong radiation field simulation signal source through a circuit, and used for receiving the high and strong radiation field simulation signals output by the high and strong radiation field simulation source and generating field intensities which are evenly distributed in an area to be tested. The multi-channel receiving device is connected with the control and data processing module through a circuit and used for detecting the field intensities in the area to be tested and transmitting the field intensities to the control and data processing module. By means of the low level scanning filed high and strong radiation field testing system, complete-machine-level low level scanning field testing can be conducted on targets like spacecrafts and aircrafts, parameters of the protective properties, like the shielding property, of the spacecrafts and the aircrafts under the HIRF condition can be obtained, and the system can also be used in protective property verification tests of automobiles, rail transit and the like under high electromagnetic environments.

Description

technical field [0001] The invention relates to an electromagnetic characteristic measurement technology, in particular to a high-intensity radiation field test system and a test method of a low-level scanning field. Background technique [0002] Electromagnetic radiation from ground control radars, commercial radios, navigation radars, and air tracking radars is called High Intensity Radiated Fields (HIRF). With the development of science and technology, traditional mechanical or electromechanical control and electromechanical indication systems for aerospace vehicles and other equipment that perform key functions have been gradually replaced by electronic flight control systems, electronic display indication systems, and full-authority digital engine controllers. These devices are obviously more sensitive to the external electromagnetic environment than traditional systems. At the same time, as more and more low-conductivity composite materials appear on new equipment, th...

AI Technical Summary

Problems solved by technology

At the same time, as more and more low-conductivity composite materials appear on new equipment, the shielding effectiveness of this type of equipment against the HIRF environment is greatly reduced

In addition, from the perspective of the external HIRF environment, the number and power of radio frequency transmitters have increased, and the number of working methods has increased, making the space electromagnetic spectrum wider and the electromagnetic field strength increased.
