哈尔滨工程大学word格式论文，基于差分演进算法的TDOA定位技术。提出了三种新的定位算法：基于TDOA的Chan-GA算法、Chan-DE算法和Chan-IDE算法。并在相同的仿真环境下进行比较，仿真结果表明，在保证种群数量的情况下，所提的算法性能稳定，能找到逼近全局最优点的解，相对于Chan算法精度更高,相对于以前的算法在保证收敛性能的前提下有更快的收敛速度。(Harbin Engineering University, word format papers, based on differential evolution algorithm TDOA positioning technology. Proposed three new localization algorithm: Based on TDOA Chan-GA algorithm, Chan-DE algorithm and Chan-IDE algorithms. And in the same simulation environment to compare simulation results show that, in the case of populations to ensure that the proposed algorithm performance and stability, can be found close to the global optimal solution, Chan algorithm with respect to higher accuracy compared to the previous algorithm convergence performance guarantee under the premise of a faster convergence.)
