摘要: 本文針對(duì)實(shí)測(cè)的雷達(dá)地雜波數(shù)據(jù),利用其分形特性,提出基于分形各種特征的信號(hào)檢測(cè)方法,并進(jìn)一步利用多重分形的概念來提取雜波的多層次分形特征。均取得較好的檢測(cè)性能。

Abstract: Real clutter data collected from land radar are fractally processed. Fractal-based methods for signal detection are presented, and the detector performances are given experimentally. Multifractal is also used to extract multilevel fractal features and further to signal detection. All the methods have better detecting performance. -
