Abstract: Background
As a kind of equipment in the field of electromagnetic compatibility testing, the application research of reverberation chamber covers airborne platforms, electronic and electrical equipment, automotive electronic components, etc. At present, the demand for radiation susceptibility testing in military and civil standards using reverberation chamber is growing, but there are significant differences in test standards, and the requirements of key indicators (such as frequency range, waveform characteristics, field uniformity, etc.) are not unified, which restricts the accuracy of product verification in high field strength environment.
Purpose
The purpose of this study is to systematically analyzes the radiation susceptibility test standards and methods of reverberation chamber in different standards, reveals the limitations of existing standards, and puts forward the solution of military and civil standards collaborative optimization, which provides the basis and guidance for product design verification.
Methods
Through standard comparison, focus on the following two research paths: first, standard comparison, sort out the domestic test standards for airborne platforms, electronic and electrical equipment, automotive electronic components, etc; second, parameter analysis, show the differences of key indicators such as frequency range, waveform characteristics, field uniformity, etc.
Results
First, standard difference. the test frequency range of military products is higher than that of civil fields, such as 40GHz; The requirements for waveform characteristics of military products and electronic and electrical equipment are simpler than others; Military products and electronic and electrical equipment require higher field uniformity (in the low frequency band) than other requirements, which is 2dB higher. Second, parameter influence. the difference in the test frequency range may lead to inconsistent sensitivity response in the high frequency band of the product; Different waveform characteristics lead to inconsistent response of products to different waveforms; The difference of field uniformity leads to the difference of construction cost of reverberation chamber.
Conclusions
It is suggested to promote the unification of key indicators of military and civilian standards, establish a standardized field strength evaluation system, and optimize military test standards. The research results can help product designers accurately grasp the key points of design verification under high field strength environment and improve the efficiency of R&D.
