Abstract

The invention discloses a method for optimal distribution of ship platform short-wave antenna space resources. The method comprises the following steps of: 1) determining index parameters which influence a short-wave system antenna layout scheme, wherein the index parameters comprise an isolation degree, a distortion degree and a field intensity limiting value; 2) establishing a short-wave systemantenna layout optimization multi-target function model by taking the isolation degree, the distortion degree and the field intensity limiting value as optimization targets; 3) determining constraintconditions of a target function model; 4) determining to-be-optimized antennas and parametrically describing available EMC layout positions; 5) generating an antenna layout initial scheme by combiningship model antenna layout; and 6) solving the short-wave antenna layout multi-target function model by utilizing a simulated annealing-based genetic algorithm, and carrying out iterative calculationto obtain optimum layout of the to-be-optimized antennas.

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...
