中文摘要:
      讨论利用接收水声信号的能量累积信息进行多传感器多目标数据关联,采用极性相关方法分析能量累积信息的变化特性,从而得到不同传感器间的多目标关联性检验准则。以声纳接收信号为对象的仿真实验表明,由所提方法计算的判别函数在同源目标和非同源目标间有明显的可分性,且在较低信噪比条件下,该方法仍可得到较好的关联效果。
英文摘要:
      An approach to data association by using the energy trace of underwater acoustic signal is proposed in this paper. The variety of energy trace is analyzed by exploiting the polar correlation rule. And a decision criterion for the correlation of multi-sensor and multi-target is derived. The simulation results of sonar-received signals demonstrate that the decision function proposed in this paper can effectively distinguish targets between identical and non-identical acoustics sources. The approach is still effective even if the signal-to-noise ratio (SNR) is low.
