摘要:

为实现高效干扰,针对多点源干扰系统的性能依赖于干扰源空间布局的问题,基于推导的任意三角形三元组天线等效辐射中心分布规律,分别对全向和非全向情况构建布阵模型,提出一种基于黄金映射策略的鲸鱼优化算法(golden mapping strategy whale optimization algorithm,GWOA)对模型进行优化求解。仿真实验表明,全向情况下正三角形布阵方式能够最大化等效辐射中心的分布区域;非全向情况下,通过控制两根天线相位差恒定,等腰直角三角形布阵方式可在约束角度范围内实现等效辐射中心分布区域的最大化。与5种经典算法相比,GWOA在收敛速度上平均提升了36.26%,稳定性平均提升了79.55%。仿真结果表明,所提算法显著优于对比算法。

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.
