Abstract: Ant cluster network architecture of multi-space-time,high-dimensional stochastic process is built based on signal detection and tracking metadata fants dustering algorithm,so that any ant individuals according to the random access signal opportunity to join the transmission path in order to reduce external interference and offset signal distortion.Based on the propagating process of GPS signal frequency domain representation of the opportunistic ant is cluster network architec ture,the generation and fusion of multi-frequency GPS weak signal body are given.A new multiband fusion GPS weak signal tracking and acquisition algorithm is proposed.Simulation results show that the proposed algorithm has obvious advantages over real-time ant clustering control,GPS weak signal acquisition sensitivity and tracking accuracy compared with the tracking acquisition algorithm without extracting weak GPS signal.

Key words: ant clustering, opportunistic control, multiband fusion, GPS weak signa, tracking and acquisition

摘要： 基于蚂蚁群集算法的信号检测与跟踪元数据,构建蚂蚁群集网络架构多时空、高维度的随机过程,使得任意蚂蚁个体根据信号的随机轨迹机会地加入传输路径,以便降低外界干扰和抵消信号失真。基于机会蚂蚁群集网络架构的GPS信号频域表征传播过程,给出多频GPS弱信号体生成和融合过程,并提出一种新的多频段融合GPS弱信号跟踪采集算法。仿真实验结果表明,与未提取GPS弱信号的跟踪采集算法相比,该算法在蚂蚁群集控制实时性、GPS弱信号采集敏感度和跟踪精度上均具有明显优势。
