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。
Aiming at the problems that the sensitivity test method of open field environment put forward in various domestic standards and experiments can not meet the needs of large-scale projectile and high field strength test, the advantages of reverberation room in test space and strong field simulation , Proposed a test method of sensitivity of radio fuze under reverberation room. This test method can also provide a methodological reference for the sensitivity test of other large equipment. The method is based on the reverberation room step-by-step operating mode and measures the critical firing field strengths of the test fuzes at different sampling points at the test frequency. The test shows that taking the minimum of the measured values at different sampling points as the threshold of the sensitivity of the radio fuze under the reverberation chamber is not only close to the measurement result under the condition of the open field but also in the two experimental environments Test results to maintain a good correlation, reflects the feasibility of this test method.
