From this method we can obtain a better signal to clutter ratio , and improve the resolution , so we can position the target accurately 對(duì)實(shí)際探測(cè)數(shù)據(jù)的分析表明,這種方法不僅可有效的抑制雜波,還可獲得目標(biāo)反射時(shí)間的準(zhǔn)確信息,為進(jìn)一步確定目標(biāo)深度提供條件。
( 4 ) after factual characteristics of targets and clutter have been studied , an approach of radar signal detection based on factual has been given and analyzed deeply , the influence caused by different window length , signal to clutter ratio ( scr ) and clutter background has been analyzed , then the monte - carlo simulation method has been used to analyze the detection performances ( 4 )研究了目標(biāo)和雜波的分形特性,深入研究了基于分形的雷達(dá)信號(hào)檢測(cè)方法,分析了不同滑窗長度、不同信雜比和雜波背景變化情況對(duì)回波分形維數(shù)的影響,采用蒙特卡羅仿真分析該檢測(cè)器的性能。
