| 摘 要： | 采用跳频编码对水声定位阵元进行编码,编码之间的互相关函数直接影响时延估计精度,提出以互相关峰最小作为编码优化目标.在上述分析的基础上,通过模拟退火算法优化对编码进行组合优化.试验结果表明,通过优化后的跳频编码对水声定位阵元进行编码,可以实现水声信号扩频,减小阵元信号间相互影响的作用.

| Abstract: | Frequency hop coding of Multi-array-elements is proposed in Underwater Acoustic positioning sys-tem, cross-correlation function of Multi-array-elements codes directly affects the precision of time delay estima-tion. Minimum peak of cross-correlation as optimization objective is Used. On the base of analysis mentioned a-bove, simulated Annealing Algorithm is used to optimize the codes. The results of experimentation show a good agreement with the theoretical analysis,and demonstrate that the method could induce interference of Multi-ar-ray-elements signals. |
