    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.
