针对国内各类标准及实验中提出的开阔场环境下敏感度测试方法无法满足线度较大弹体及高场强测试需要的问题，利用混响室在测试空间和强场模拟等方面的优势，提出混响室条件下无线电引信敏感度测试方法。测试方法是基于混响室步进工作模式，引入归一化场强这一物理量对混响室中受试引信敏感发火临界场强进行测算。实验证明，取各测试频点在不同采样点处测量值的最小值作为混响室条件下无线电引信的敏感度阈值时，混响室敏感度测试结果数值上最接近于标准均匀场条件下测得的敏感度阈值，同时进行不同搅拌器配置下该类引信的混响室敏感度测试。结果表明：搅拌器组合步进工作测量精度高于各搅拌器独立搅拌，而竖搅拌器独立步进工作时测试精度高于横搅拌器独立工作。

The susceptibility test methods used in current standard experiments in the uniform field environment cannot meet the requirements of tests for large-size proj ectile bodies and high field strength.We propose a new susceptibility test method for the radio fuze,which takes advantage of the reverberation chamber's test space and strong field simulation.The method is based on the re-verberation chamber tuned-mode and the normalized field strength is introduced to figure up the susceptibility threshold.The result of the experiments shows that when we take the minimum value among the measured values of the different sampling points as the susceptibility threshold in the test frequency,the threshold is numerically close to the measurement result of uniform field environment.And though a series of susceptibility tests with different stirrers,the result can be concluded that the performance is best when the two stirrers work in group.When the stirrers in the reverberation chamber work independently,the vertical stirrer performs better than the hori-zontal one.
