Ship radiated-noise research based on the LOFAR spectrum and DEMON spectrum characteristics

XIONG Zi-ying,ZHU Xi-qing(China Ship Scientific Research Centre,Wuxi 214082,China)  
The key problem of the target identification is target characteristic abstraction.In this paper,the spectrum and the frequency characteristics of the ship radiated-noise were analyzed by using LOFAR and DEMON method.The introduction of the method and some theoretical analysis are given.Emulational signal and real signal are investigated respectively and some useful results which are practical for engineering are presented.It provided effective criterion for the ship detection and identification.
