中文摘要：
研究了水下潜艇对空中反潜飞机的警戒和探测问题。针对潜艇和反潜机对抗中的信息不对称性，建立了空中声源航行的多普勒效应和水下声传播模型，提出了基于时延估计的空中声源水下检测方法，对增强潜艇预警空中声源的能力进行了探讨。这对于潜艇今后增强预警空中声源的能力，改善潜艇和反潜飞机对抗中的不对称性具有指导意义。
英文摘要：
Warning and detecting artisubmarine aircraft by submarine is studied. Aiming at the information dissymmetry in the rivalry between submarine and antisubmarine aircraft, Doppler-Shift Frequency effect and underwater acoustic propagation from aircraft are modeled. The underwater detection method of air acoustic source is proposed. And, the problem about how to enhance acoustic early-wanting ability of submarine against antisubmarine aircraft is discussed, which has guiding signigicance for changing dissymmetry in countermeasure.
