Electric stealth of marine robotics against non-contact seabed mines

Abstract

Object and purpose of research. This paper investigates marine robots to estimate possible effect of environmental changes upon their stealth against local electrometric seabed threats, like non-contact mines. Materials and methods. This paper continues the series of studies analyzing stealth of marine objects as per system-approach methodology and theoretical principles of optimal signal identification against noisy background. Main results. The paper discusses possible ways for improving electric stealth of marine robotics and suggests a mathematical model for estimation of possible spectral parameters of near-seabed electric interference depending on the environment. The study yielded the estimates of possible electrometric detection for local seabed assets depending on electric dipole moment of the target, electric conductance of sea water and intensity of electric interference near the seabed. Conclusion. The results of these studies pave way to the development of electric stealth standards for marine robotics, as well as to the development of marine robotic technology control methods taking into account the necessity to ensure their stealth for non-contact seabed mines with electric fuses.
