Abstract

To verify the feasibility of equipping electric field sensors on fast motion platforms to detect ship targets

this manuscript analyzes the mechanism of background electric field generation on fast motion platforms

builds a high-speed motion platform electric field detection system based on surface speedboats

and conducts real boat sea measurement experiments. The background electric field of speedboats at different positions

engine operating conditions

and sailing speeds is measured

and the measurement results are analyzed. By analyzing the experimental data at sea

it is found that the background electric field comes from: 1) the motion induced electric field of the speedboat platform

2) the corrosion and electromagnetic radiation of the speedboat itself. The background electric field has high energy in the frequency band below 1Hz (static electric field)

so the ship’s electrostatic field is not suitable as a detection signal source. When the speed is below 20 knots

the background electric field spectral density of the speedboat detection platform in the 1-30Hz frequency band is about 0.4μV/$\sqrt{\mathrm{Hz}}$

so the ship’s shaft frequency electric field can be used as the target signal source. To verify the feasibility of electric field detection on the speedboat platform

electric field targets of 100A·m were detected at different speeds of 5~15kn

with a detection distance of 1500m. Therefore

it is practical to use a fast motion platform equipped with electric field sensors to detect the ship’s electric field.

(in Chinese) DOI: 10.3969/j.issn.1000-1093.2021.04.016 http://doi.org/10.3969/j.issn.1000-1093.2021.04.016 A sliding threshold detection method based on Rao detector is proposed to detect the ship's shaft-rate electric field at a low SNR in non-Gaussian noise environment. A signal model is established based on the characteristics of signal source, and a noise model is established based on Gaussian mixture model (GMM) after analyzing its non-Gaussian characteristics measured by a floating platform. In the detection process, the parameters of GMM and the Rao detection value are computed in real time; the mean value of previous Rao detection values is regarded as the sliding threshold. The simulation method is first used to verify the proposed method. The results show that the detection performance of Rao detector is better than that of energy detector. Then the measured ship data is used to compare the Rao sliding threshold method and the sliding power spectrum method. The results show that the proposed method is better in decreasing the non-Gaussian environment noise and has a better detection performance than the sliding power spectrum method.

In the analysis, the dimension of tracking filter is reduced while ensuring the modeling accuracy and the stability of filtering algorithm.A progressive update extended Kalman filter (PUEKF) was designed for the simulation analysis and experimental verification of ship electric field tracking. The results show that a electric field model with a small number of point charges can be used to replace the complex ship electric field point charge array model in ship electric field tracking, which has high tracking accuracy. The PUEKF can effectively improve the initial error tolerance range and has high filtering stability. The tracking error is less than 10m in the range of 500 m. The PUEKF has low computational cost, which is suitable for engineering applications for the ship electric field tracking. Key
