Abstract:

In order to achieve efficient interference, in response to the issue that the performance of the multi-point source interference system depends on the spatial layout of the interference source, based on the derived distribution law of the equivalent radiation center of any triangular triplet antenna, the array model is constructed for omnidirectional and non-omnidirectional situations respectively, and a golden mapping strategy whale optimization algorithm (GWOA) is proposed to optimize and solve the model. The simulation experiments show that the equilateral triangle array can maximize the distribution area of the equivalent radiation center in the omnidirectional case. In the non-omnidirectional case, by controlling the constant phase difference between the two antennas, the isosceles right-angle triangular array can maximize the distribution area of the equivalent radiation center within the constraint angle range. Compared with the five classical algorithms, GWOA has an average increase of 36.26 % in convergence speed and an average increase of 79.55 % in stability. The simulation results indicate that the proposed algorithm is significantly better than the comparison algorithms.
