The invention discloses a method for optimally allocating short-wave multi-antenna space resources on a ship platform, comprising the following steps: 1) determining index parameters that affect the antenna layout scheme of a short-wave system, including isolation, distortion, and field strength limits; 2) using The isolation, distortion and field strength limits are the optimization goals, and the multi-objective function model for antenna layout optimization of the short-wave system is established; 3) Determine the constraints of the objective function model; 4) Define the antennas that need to be optimized, and parametrically describe the available EMC layout position; 5) Combining with the ship model antenna layout, an initial antenna layout plan is generated; 6) Using the genetic algorithm based on simulated annealing to solve the multi-objective function model of the shortwave antenna layout, and performing iterative calculations to obtain the optimal layout of the antenna that needs to be optimized .
Description
technical field [0001] The invention relates to ship electromagnetic compatibility technology, in particular to a method for optimally allocating short-wave multi-antenna space resources on a ship platform. 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. There are as many as 50, 60 or more antennas on a typical destroyer. The use of a large number of antennas puts forward higher requirements for antenna layout. If the antenna is improperly arranged, on the one hand, it will cause serious electromagnetic interference to these devices or systems, and on the other hand, it will have a certain impact on the working perform...
