    Abstract
  • For areas with scarce gravity anomaly data, this paper proposes to use fractal Brownian motion (FBM) fractal interpolation method to reconstruct the gravity anomaly random field, achieving the generation of gravity anomaly reference maps that can be used for underwater gravity assisted navigation. The experimental results indicate that the fractal interpolation method is feasible as a rough interpolation method and can provide theoretical reference for the implementation of underwater gravity assisted navigation systems.
