Abstract

The target localization equations base on time difference of arrival (TDOA) are highly nonlinear and nonconvex, leading to challenges in traditional mathematical methods, such as poor localization robustness, a sharp decline in accuracy with increased noise, and difficulty in ensuring convergence. Metaheuristic algorithms have great potential for solving complex, multimodal, high-dimensional, nonlinear optimization problems. Inspired by the characteristics of metaheuristic algorithms, an enhanced secretary bird optimizer is proposed to address the shortcomings of existing TDOA-based localization algorithms in this paper. Simulation results show that the proposed method exhibits higher robustness and localization accuracy in different simulation scenarios, compared to traditional mathematical algorithms and other metaheuristic algorithms.

一种基于TDOA的增强秘书鸟优化算法

基于到达时间差（TDOA）的目标定位方程具有高度非线性和非凸性，这给传统数学方法带来了定位鲁棒性差、精度随噪声增加而急剧下降、难以保证收敛等挑战。元启发式算法在解决复杂、多模态、高维、非线性优化问题方面具有很大的潜力。摘要针对现有基于tdoa的定位算法存在的不足，利用元启发式算法的特点，提出了一种改进的秘书鸟优化算法。仿真结果表明，与传统数学算法和其他元启发式算法相比，该方法在不同仿真场景下具有更高的鲁棒性和定位精度。
