摘要
针对引信敏感度分步测试方法工作量大、测试时间长等问题,提出了基于位置替代法的无线电引信混响室敏感度测试方法。利用混响室统计均匀的特性,将场强测试设备与受试设备同时置于混响室内进行测试,用测试位置平均场强替代引信受试位置场强,从而得到引信敏感度阈值。试验结果表明:各测试频点在不同采样点处测量值的平均值与均匀场测试结果相关性最好,相关系数可达95%,最小值与均匀场测试结果误差最小,其相对误差在3 d B范围内。与分步测试方法相比,该测试方法避免了试验中对受试设备的移动,减小了工作量,具有更好的实用性。
Since the step-by-step susceptibility test method for radio fuses in reverberation chamber has the disadvantages of heavy load and time consuming, we proposed a susceptibility test method based on position substitution. According to the statistical uniformity of reverberation chamber, we put equipment under test （EUT） and field test equipment together at the same time in radio fuse tests. Then, using the average field intensity at the test position to substitute the EUT＇s field intensity, we calculated the sensitivity threshold of the radio fuse. The experimental results show that, among the meas- ured values at different sampling points and test frequencies, the average value has the best relativity to the test result in uniform field： the correlation coefficient is about 95%. In addition, the minimum value has the least error compared to the test results in uniform field, which is within 3 dB. Compared with the step-by-step susceptibility test method, the proposed method avoids movement of EUT in tests and has a higher practicability.
