Probability statistical method of assisting electromagnetic compatibility index decision-making

The index of equipment and system in the electromagnetic compatibility standards is usually suitable to many kinds of flats, and it is to be right chosen and clip in the actual application based on the engineering practice, or excess design and absent design will bring waste of resource or electromagnetic interference. To the naval ships, it is difficult to carry through accurate modeling adopting traditional numerical simulation method. Recur to probability statistical analysis, we research the rule of electromagnetic emission of potential interferential equipment and sensitive characteristic of potential sensitive equipment, by which forecast the probability of resulting in electromagnetic interference and farther to process analysis and decision-making of equipment and system index. This method on the one hand fully makes use of engineering historical data which have preferable engineering value and directive sense, while on the other hand it avoids abundant numerical modeling which is more simple and feasible.
