Abstract

The invention relates to a method for rapidly generating an interference matrix between ship shortwave systems. The method comprises the following steps: 1, according to interaction between radiation frequency equipment and sensitive frequency equipment in ship shortwave system frequency equipment, establishing a ship shortwave system interference incidence matrix; 2, solving interference energy which is received by the sensitive frequency equipment in the shortwave systems and is radiated by the radiation frequency equipment; 3, establishing multi-factor criterions of the interference received by the sensitive frequency equipment in the shortwave systems to an electromagnetic compatible state; 4, on the basis of the multi-factor criterions on the electromagnetic compatible state in the ship shortwave systems, completing a rough screening stage of generation of the interference matrix between the shortwave systems by utilizing a four-step classified screening prediction method and forming a primary interference matrix between the ship shortwave systems; 5, completing a fine screening stage of generation of the interference matrix between the shortwave systems and finally establishing the interference matrix between the ship shortwave systems. According to the method, rough screening and fine screening are combined to gradually refine so as to realize rapid generation of the interference matrix between the shortwave systems and high efficiency and high accuracy are achieved.

Description

technical field [0001] The invention belongs to the field of electromagnetic compatibility prediction, and in particular relates to a method for quickly generating an interference matrix between ship short-wave systems. Background technique [0002] In order to realize the normal communication between ships and shores, ships and ships, several antennas working in different frequency bands are installed on the ship platform, together with navigation, electronic warfare and radar antennas, as well as various electronic equipment and weapons The system constitutes the complex electromagnetic environment of the ship platform. Among all kinds of antennas, short-wave communication antennas are not only the focus of the control of electromagnetic radiation hazards of the whole ship, but also the focus of the design of electromagnetic compatibility control of the whole ship due to factors such as large number, limited layout, limited frequency band resources, and high transmission p...
