  • 摘要: 針對(duì)陣元間互耦效應(yīng)導(dǎo)致嵌套陣列測(cè)向性能下降的問(wèn)題,該文提出兩種不同的平移嵌套陣列結(jié)構(gòu),在保證產(chǎn)生虛擬陣列無(wú)孔的條件下,通過(guò)對(duì)原二級(jí)嵌套陣列陣元位置進(jìn)行調(diào)整,形成平移嵌套陣列,提高了原二級(jí)嵌套陣列的稀疏性,降低了陣元間的互耦效應(yīng),擴(kuò)展了原嵌套陣列的測(cè)向自由度。在空間輻射源數(shù)目未知條件下,建立了平移嵌套陣列稀疏貝葉斯學(xué)習(xí)(SBL)算法模型,對(duì)形成的虛擬陣列接收數(shù)據(jù)進(jìn)行處理,獲得角度估計(jì),有效提高了原嵌套陣列測(cè)向算法的測(cè)向性能。仿真實(shí)驗(yàn)表明,平移嵌套陣列自由度高于原嵌套陣列,在低信噪比、小快拍數(shù)、存在互耦影響條件下,基于稀疏貝葉斯學(xué)習(xí)的平移嵌套陣列測(cè)向算法測(cè)向精度優(yōu)于原嵌套陣列測(cè)向算法,并且提高了原嵌套陣列測(cè)向算法的角度分辨率。
