摘　　要：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,提出了混响室条件下无线电引信敏感度测试方法。这种测试方法也可以为其他大型装备的敏感度测试提供方法借鉴。该方法基于混响室步进工作模式,测量受试引信在测试频点不同采样点处的临界发火场强。试验证明,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,不仅在数值上接近于开阔场条件下的测量结果,而且两种实验环境的测试结果保持了很好的相关性,体现了这种测试方法的可行性。The susceptibility test methods to current standard and experimental in the open field environment couldn＇t meet the needs of the greater size projectile bodies and high field strength tests. In consideration of the preponderance of re- verberation chamber in test space and strong field simulation, we propose a new susceptibility test method for the radio fuze in reverberation chamber. This test method also provides a reference for other large equipments＇ susceptibility test. The method is based on the reverberation chamber tuned-mode. In the test frequency , the critical initiating field of the fuze under tested is measured in different sampling points. The result of the experiment 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 nu- merically close with the measurement result of open field environment and the test result of two test environments have a good linear correlation. These conclusions reflect that this test method is feasible.
