Layout Scheme of Measuring Array in Ships' Electric Field Measuring Station

To evaluate the stealth effect of ships' electric field and provide a theoretical basis for designing and establishing of ship's electric field measuring station, the influences of measuring sensor array's width and spacing between sensors in the station on the precision of related depth extrapolation processing were analyzed, and a reasoned principle for the layout scheme of sensor array was presented. The result shows that when measuring depth is 10 m, the sensor array should be as wide as 4.87 times the width of ship, and the spacing between sensors should be less than 8 m; similarly under the condition that the measuring depth is 20 m, the sensor array should be as wide as 10.10 times the width of ship, and the spacing between sensors should be less than 16 m. As the measuring depth grows, the whole sensor array and the spacing between sensors should be increased.
