  1. ( 5 ) mfpic ( matched field postbeamformer interference canceller ) is proposed to cancel tow ship ' s noise. the advantage of mfpic is that it can be used to cancel the tow ship ' s noise for all arrival directions. furthermore, this new approach can be used to detect weak target, which has the same bearing angle of a strong interference

    （ 5 ）將平面波波束形成后干擾抵消與匹配場處理技術進行有機結合，探索性地提出了拖線陣聲納本艦干擾的匹配場抵消方法和匹配場處理后的干擾抵消方法，為本艦多途干擾抵消、水面強干擾抑制和水下弱目標檢測提供了新的技術途徑。
  2.
