雷達數(shù)據(jù)的多重分形模型
RADAR DATA ANALYSIS WITH MULTI-FRACTAL METHODS
-
摘要: 本文將多重分形的分析方法引入到雷達雜波的分析中,直接從雜波數(shù)據(jù)本身出發(fā),研究其具有的共性;并分別對雜散數(shù)據(jù)和帶目標回波數(shù)據(jù)進行了分析,提取了它們的多重分形特征。結果表明在一定的尺度范圍內,單純的雷達雜波具有分形的特征,而帶目標回波數(shù)據(jù)則存在分形的失配性,從而提供了一種對目標進行粗檢測和判決的新方法。Abstract: Multi-fractal methods are introduced to radar clutters analysis in this paper to find general characteristics of clutters. Clutters and echoes from targets are analyzed respectively. The results show that the radar clutters are a kind of generalized frctal signals in some degree, and echoes from targets do not match with the fractal model. This fact leads to a new way to detect targets.
