用单个矢量水听器基于DEMON线谱的双目标分辨
Identifying two targets by a single vector hydrophone based on the DEMON spectrum
  
中文摘要:
      不同目标的解调线谱频率是不同的。本文提出了一种在DEMON谱域内对双目标测向的方法,它具有较好的抗相干及非相干干扰能力,表明单个矢量水听器也能分辨多目标。文中叙述了利用DEMON线谱测向的原理,给出了轴频提取及双目标DEMON线谱分离的方法,对DEMON线谱区分双目标的能力做了仿真分析。
英文摘要:
      Different target has different DEMON spectrum. Based on this characteristic, a new method to estimate the direction of two different targets is brought forward in this paper, which can efficiently suppress both coherent and un-coherent interferences. The method uses a single vector hydrophone and demonstrates the ability of such single hydrophone to identify multi-targets. The principle of DOA estimation based on the DEMON spectrum is specified; The method to pick-up the axial frequency and to identify the DEMON spectra belonging to two targets is given; The capability of identifying two different targets based on the DEMON spectrum is analyzed.
