基于Q-MMSPF的海杂波多重分形互相关分析和目标检测
Multifractal cross-correlation analysis of sea clutter and target detection based on Q-MMSPF
摘要
Abstract
A novel method,the Qth order Mixed Moment Structure Partition Function (Q-MMSPF) method,is proposed for the detection oflong-range cross-correlations and muhifractality.With this method,the multifractal cross-correlation characteristic of sea clutters was investigated.The analysis,based on the real sea clutter data,shows that the cross-correlation muhifmctality is quite weaker between the two sea clutter series,and the multifractality is significant between two time series of target plus sea clutter,whereas the multifractality is in the middle for the case,which is between target time series and sea clutter time ones.Consequently,an approach was suggested to detect the targets in sea clutter.The test results show that the target can be clearly distinguished from the sea clutter background with the proposed feature-based method.关键词
