Inverse Synthetic Aperture Radar Imaging with Non-Coherent Short Pulse Radar and Its Sparse Recovery

  • 摘要: 短脈沖非相參雷達(dá)(NCSP)的輻射源輸出微波脈沖持續(xù)時(shí)間短,針對(duì)于高速運(yùn)動(dòng)目標(biāo)而言,其脈沖持續(xù)時(shí)間內(nèi)的目標(biāo)運(yùn)動(dòng)可忽略不計(jì),對(duì)回波信號(hào)不需進(jìn)行專門(mén)的脈沖內(nèi)運(yùn)動(dòng)補(bǔ)償。為了利用短脈沖非相參雷達(dá)信號(hào)進(jìn)行逆合成孔徑雷達(dá)成像,該文應(yīng)用補(bǔ)償相參處理的方法,去除輻射信號(hào)包絡(luò)時(shí)間不確定性和初始相位的不確定性影響,在常規(guī)方法進(jìn)行包絡(luò)對(duì)齊和初相補(bǔ)償后可利用距離-多普勒(RD)方法進(jìn)行逆合成孔徑雷達(dá)成像,仿真驗(yàn)證了補(bǔ)償后信號(hào)成像的可行性。然而,短脈沖非相參雷達(dá)的載頻隨機(jī)抖動(dòng)的因素會(huì)導(dǎo)致距離-多普勒成像結(jié)果在多普勒維度產(chǎn)生隨機(jī)調(diào)制的旁瓣,影響成像的質(zhì)量。利用稀疏恢復(fù)技術(shù),在成像空間中對(duì)目標(biāo)的散射中心進(jìn)行稀疏重構(gòu),利用正交匹配追蹤(OMP)算法和稀疏貝葉斯學(xué)習(xí)(SBL)算法進(jìn)行成像,從而實(shí)現(xiàn)了抑制非相參因素引起的成像旁瓣,改進(jìn)了成像質(zhì)量,通過(guò)仿真驗(yàn)證了方法可行性。
