Uncertainty analysis method for HIRF test of civil aircraft system

Utilizing the reverberation chamber to build a system-level HIRF test system for civil aircraft, and the influencing factors of the uncertainty of the test system were qualitatively analyzed through the establishment of a mathematical model. The uncertainty is extended by quantitative analysis of the mathematical model, the measurement uncertainty of the HIRF test system is calculated, and the uncertainty factor influence is controlled to ensure the accuracy and reliability of the test results.
