【摘要】：彈道導(dǎo)彈識(shí)別是彈道防御系統(tǒng)中的核心問題之一,直接關(guān)系到導(dǎo)彈防御系統(tǒng)的成敗。如果能對(duì)彈道目標(biāo)成像,則能獲得關(guān)于目標(biāo)結(jié)構(gòu)更為豐富的信息。由于彈道目標(biāo)具有高速自旋的特點(diǎn),因此基于轉(zhuǎn)臺(tái)模型的逆合成孔徑雷達(dá)成像技術(shù)對(duì)高速自旋目標(biāo)成像是失效的。針對(duì)該問題,詳細(xì)分析了彈道目標(biāo)回波模型,并研究了彈道目標(biāo)時(shí)頻圖的調(diào)制規(guī)律,在此基礎(chǔ)上,提出一種基于微多普勒信息的彈道目標(biāo)成像方法,實(shí)現(xiàn)了對(duì)彈道目標(biāo)二維強(qiáng)散射中心的重構(gòu),仿真數(shù)據(jù)處理結(jié)果證明了所提方法的有效性。
[Abstract]:Ballistic missile identification is one of the core problems in ballistic defense system, which is directly related to the success or failure of missile defense system. Because the ballistic target has the characteristics of high speed spin, the inverse synthetic Aperture Radar imaging technology based on the turntable model is ineffective for the imaging of the high speed spin target. The echo model of ballistic target is analyzed in detail, and the modulation law of time-frequency diagram of ballistic target is studied. On this basis, a new imaging method of ballistic target based on micro-Doppler information is proposed. The reconstruction of two-dimensional strong scattering center of ballistic target is realized, and the validity of the proposed method is proved by the simulation data processing.
