摘　　要：基于对电磁波传播特性实验原理和实验内容的分析,设计了一套水下电磁波频率变化特性实验方案,并进行了水池实验。经数据处理后,给出了电磁波传播过程中频率变化特性水池实验结果,并与理论仿真结果作了对比,结果表明,实测数据与理论值存在一定误差,但实测数据拟合曲线与理论曲线的变化趋势基本一致,验证了本套实验方案的可行性。最后指出了存在的问题及下一步研究方向,为水下主动变频电磁探测系统的研制提供理论和实验依据。An experimental scheme was designed for exploring frequency variation characteristics of underwater elec- tromagnetic wave based on the analyses of experimental principle and experiment items of electromagnetic wave propagation characteristics, and a water-tank experiment was performed. The results after data processing and quadratic polynomial fitting are given, and are compared with simulation ones. Conclusions are drawn that the theoretical values show some error to the measured data, but the fitting curve of the measured data show consistent trend with the theo- retical curve, which verifies the feasibility of the proposed scheme. In addition, some existing problems and further re- search topics are presented.
