Ship electromagnetic environment characteristic analysis determination method

Abstract

The invention relates to an analysis and determination method of electromagnetic environment characteristics of a war vessel. Aiming at electro-magnetic compatibility moorage of the war vessel, according to the conduction and radiation electromagnet field spectra test data tested by the existing standard code method in running trial, after classified according to identical measuring point of war vessels of the same type, the field intensity bar diagram, subsection envelope, fitting in segment of spectra are performed thereafter to calculate the characteristic fitting curve and the expression. The statistical description quantity value is determined. The peak values and the average values of subsection envelope and characteristic fitting are calculated according to the segmental terminal frequency so as to obtain the maximal and the average envelope lines, and the fitting line of frame-frequency characteristics of electric field and magnetic field of various measuring points. The invention can express in quantification the frame-frequency characteristics of the electromagnetic environment test data of the war vessel so as to obtain the quantification expression mode of the electromagnet field frame-frequency characteristics in the critical area of the war vessel. The analysis and determination method provided by the invention provides reference basis for determining electromagnetic environment characteristics of the war vessel, and researching and modifying the national relevant standard limits.

Description

technical field [0001] The invention belongs to the technical field of ship electromagnetic compatibility, and specifically relates to a method for comparing, analyzing and determining ship electromagnetic environment characteristics based on ship electromagnetic environment test data, which can be used for various surface ships, underwater submarines and other Amplitude-frequency characteristic analysis of radiated and conducted electromagnetic field spectrum data of weapon platform. Background technique [0002] In order to protect the safety of personnel, armaments and fuel on ships, submarines or other large-scale weapon platforms, and ensure the normal operation of communication equipment and electromagnetic sensitive equipment on board, it is necessary to design and verify the electromagnetic environment level in key areas of these platforms, that is, the strength of the electromagnetic field. The main method currently adopted is to use special instruments and equipmen...

Problems solved by technology

However, in actual tests, it is often found that these existing standards are based on the electromagnetic characteristics of equipment in the 1960s, which are quite different from the current equipment characteristics.

Moreover, the electromagnetic radiation characteristics of existing shipboard power electronic equipment and the layout method of radiation sources are not consistent with the original ships, and the measured electromagnetic environment data often lack compliance with the existing standard limits
