Adaptive Matched Filter Detector Based on Power Median and Normalized Sample Covariance Matrix

  • 摘要: 在非均勻海雜波環(huán)境中,參考單元中的異常單元限制了采樣協(xié)方差矩陣(SCM)的估計性能,從而影響了傳統(tǒng)自適應(yīng)匹配濾波(AMF)檢測器的檢測性能。而考慮刪除異常單元的方法在參考單元數(shù)目有限時可能導(dǎo)致矩陣的奇異性。鑒于此,在保持參考單元數(shù)目不變條件下,該文設(shè)計一種基于功率中值與歸一化采樣協(xié)方差矩陣(MNSCM)的估計方法,并將其與匹配濾波器(MF)相結(jié)合,構(gòu)造一種新型的自適應(yīng)匹配濾波檢測器。與傳統(tǒng)的自適應(yīng)匹配濾波相比,該文設(shè)計的檢測器在實測和仿真海雜波數(shù)據(jù)條件下均具有明顯的性能優(yōu)勢。
