罗兰C磁天线在鱼雷导航定位中的应用

内容简介：为了探讨鱼雷使用罗兰 C 磁天线实现水下导航定位的可行性,介绍了罗兰 C 全向磁天线的工作原理,分析了罗兰 C 信号在传播过程中磁场信号和电场信号的场强衰减规律,并进行了数学仿真.结果表明,在1000 km距离上,利用磁天线在海水中4~5 m 深度接收信号具有较高的信噪比,能够满足水下定位解算要求.试验也验证了鱼雷在浅层水域(深度小于5 m)水下接收罗兰 C 信号实现定位解算是可行的,进一步证明了仿真结果的正确性.本文研究可为罗兰 C 磁天线在鱼雷浅层水域水下导航定位提供理论依据.

Abstract：For arguing the feasibility of torpedo underwater localization and navigation with Loran-C signal received by H-field antenna, the principle of omnidirectional H-field antenna is introduced, the field intensity attenuation laws of the H-field and E-field signals in propagation of Loran-C signal are analyzed. Simulation results indicate that H-field antenna can receive Loran-C signals with high signal-to-noise ratio(SNR), meeting the requirements of underwa-ter localization solution. Experimental results show that H-field antenna can receive the signals with higher SNR at the depth of 4~5 m underwater over a distance of 1 000 km. Test confirms that the localization solution can be obtained with Loran-C signal received by H-field antenna in the depth less than 5 m underwater, which verifies the correctness of the simulation. This study may provide a theoretical basis for torpedo underwater navigation with H-field antenna.
