Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] A method for optimizing the allocation of electromagnetic compatibility indicators based on a digital model of the present invention uses four steps to optimize the allocation of indicators. In this method, the digitalization of the utility-cost ratio relationship involved in the rectification of each of the three elements of electromagnetic compatibility model, extracting the marginal utility of each rectification element in it. According to the principle of diminishing marginal utility of rectification effects in actual situations, when the sum of each sub-indicator meets the requirements of the overall indicator, when the marginal utility of each element is equal, the optimal effect of indicator allocation can be achieved. The four steps refer to:

[0015] The first step: analyze the frequency of the interference frequency point and obtain the over...

Abstract

The invention discloses a digital model-based method for optimizing and allocating electromagnetic compatibility indexes. The technical scheme comprises the following steps of: analyzing the frequency of interference frequency points and simulating by using a computer to obtain an overall reformation index; optimizing and simulating adjustable factors, and combining the actual expense required inthe engineering to obtain a digital model of a utility-expense ratio relation; extracting marginal utility curves of the adjustable factors based on the model; and obtaining the optimal allocation indexes according to an equimarginal utility principle. In the index allocation, the marginal utility of each reformation factor is extracted according to the utility-expense ratio relation in the process of reforming each factor of three electromagnetic compatibility factors. According to a principle that the marginal utility of the reformation effect is gradually decreased in the practical situation, under the condition that the sum of sub-indexes meets the requirement of an overall index, when the marginal utility of each factor is equal, the optimum effect of the index allocation can be achieved.

Description

technical field [0001] The invention relates to a method for allocating electromagnetic compatibility indexes, in particular, a method for optimally allocating electromagnetic compatibility indexes based on a digital model combined with the principle of maximum utility. Background technique [0002] The airborne communication platform system includes multiple sets of transmitting and receiving equipment, high-power transmitters and high-sensitivity receivers are installed in a limited space, and the electromagnetic signals are dense, which may cause serious interference between communication equipment in this local space. Interference with each other, resulting in a decline in the performance of communication equipment. In order to improve the performance of electromagnetic compatibility, it is usually necessary to start with the three elements of electromagnetic compatibility: interfering equipment, interference path, and disturbed equipment. For general electronic and ele...
