一种水下电磁测距的新方法
A New Method for Underwater Electromagnetic Passive Ranging
摘要
Abstract
Based on the attenuation and phase-shifting as function of propagation range of underwater electromagnetic wave, the new ranging method with the phase ratio picked out from receiving signals is proposed. Two ways, the direct range is made use of on the foresight signal and the indirect range is made use of on the arbitrary signal by the phase ratio, are discussed. Verified through the underwater test in a lab pool after calculation, the underwater electromagnetic passive range-measuring via single station not only can be brought into practice, but also the better distance resolution and range precision can be acquired to make use of the propagation phase shift of the signal which is radiated by moving target关键词
