Abstract

Feature extraction of underwater targets and line spectrum comparison are the key of the target fusion. The changing characteristics of the ocean noise field and individual differences of receiving arrays make the line spectrum feature extraction of underwater target unstable, which leads to the target comparison misjudgment. To improve the correct rate and stability of the sea target similarity judgment, this paper presents a method of target similarity judgment based on the LOFAR spectrum feature. It extracts line spectrum feature information from the LOFAR spectrums of ship radiated noise, calculates the area of the peaks extracted out, extends peaks and finally get the judgment result using the multiple asymmetric comparison method. This paper applied this method to the multi-type target data measured at sea and obtained satisfactory effect.
