Target Detection Method Based on Fractional Lower Order Locally Optimum Detector

  • 摘要: :針對傳統(tǒng)局部最優(yōu)檢測器在顯著非高斯雜波背景下導(dǎo)致檢測性能下降的問題,該文提出一種分數(shù)低階局部最優(yōu)雷達目標檢測方法。首先對局部最優(yōu)檢測器的模型進行簡化,在此基礎(chǔ)上,根據(jù)分數(shù)低階統(tǒng)計量理論,利用分數(shù)低階相關(guān)矩陣描述雜波的相關(guān)特征,并以分數(shù)低階二次型作為局部最優(yōu)檢測器的權(quán)值,改善了顯著非高斯雜波背景下的雷達目標檢測性能。利用仿真數(shù)據(jù)和IPIX雷達數(shù)據(jù)進行實驗分析,結(jié)果表明,針對顯著的非高斯雜波背景下的弱目標信號,相對于傳統(tǒng)的局部最優(yōu)檢測方法,該文方法的檢測性能顯著提高。
