Underwater target electromagnetic detection technology has made great progress in recent years due to China’s continuous interest in marine defense and the difficulty of traditional acoustic detection of underwater targets. Axial-frequency electromagnetic field is an important research content in underwater target electromagnetic detection technology. At present，the relevant simulation research is primarily based on measurement line analysis， and there is still relatively little research on the spatial distribution characteristics of axial-frequency electromagnetic fields measured by the observation network，as well as the detection range. In this paper，problems existing in previous studies are analyzed，and a time-harmonic horizontal electric dipole is used as the equivalent field source. Based on integral equation method，numerical simulation of the distribution characteristics of axial-frequency electromagnetic field for detection devices located on seafloor are performed. Then，the detection range of axial-frequency electric field and that of magnetic field based on seafloor observation network are compared and analyzed. Besides，the influence of target traveling orientation on axial frequency electromagnetic field distribution is discussed. Finally，the future research ideas are prospected.
