ABSTRACT An improved whale optimization algorithm (IWOA) is presented to estimate the surface duct. First, the iteration and selection mechanism in whale optimization algorithm (WOA) are modified to avoid local optimum. Then, orthogonal crossover is embedded into WOA to improve its exploration ability. Finally, the IWOA is applied to benchmark functions and the optimization problem of surface duct to test the performance of IWOA, and the results are compared with those of genetic algorithm (GA), WOA and variant WOA. The comparison results show that IWOA has best accuracy and stability for almost all the benchmark functions and the inversion of the surface duct.

使用改进的鲸鱼优化算法反演雷达海杂波的表面导管

摘要 提出了一种改进的鲸鱼优化算法（IWOA）来估计表面管道。首先，修改鲸鱼优化算法（WOA）中的迭代和选择机制以避免局部最优。然后，将正交交叉嵌入到 WOA 中以提高其探索能力。最后，将IWOA应用于基准函数和表面风道优化问题来测试IWOA的性能，并将结果与​​遗传算法(GA)、WOA和变体WOA的结果进行比较。对比结果表明，IWOA对几乎所有的基准函数和表面风道反演都具有最好的精度和稳定性。
