Abstract

The method for quickly generating an interference matrix between ship short-wave systems comprises the following steps: 1) establishing a ship short-wave system interference correlation matrix according to the interaction between radiation frequency devices and sensitive frequency devices in ship short-wave system frequency devices; 2) Solve the interference energy radiated by the sensitive frequency equipment of the short-wave system received by the radiation equipment; 3) Establish the multi-factor criterion for the electromagnetic compatibility state of the interference received by the sensitive frequency equipment in the short-wave system; 4) Based on the ship's short-wave The multi-factor criterion of the electromagnetic compatibility state in the system, using the four-step hierarchical screening and prediction method to complete the "rough screening" stage of the interference matrix generation of the short-wave system, and form the preliminary interference matrix of the short-wave system of the ship; In the "fine screening" stage, the interference matrix of the ship's short-wave system is finally established. The invention adopts the combination of "coarse screening and fine screening" to successively refine to realize the rapid generation of short-wave system interference matrix, with high efficiency and high accuracy.

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...
