外場實測數(shù)據(jù)的艦船目標ISAR成像
ISAR SHIP IMAGING OF REAL DATA
-
摘要: 有關飛機目標的ISAR成像國內已有較深入的研究。對水面艦船的雷達成像在國防上同樣有重要意義,但國內對艦船的ISAR成像的研究,基本上為空白狀態(tài)。雖然艦船成像與飛機成像在基本原理上沒有區(qū)別,但由于海水的波動,使艦船的姿態(tài)變化比較復雜,有必要作專門的研究。該文是作者利用外場實測數(shù)據(jù),針對艦船運動的特殊性,提出基于Clean的調幅-線性調頻(AM-LFM)信號參數(shù)估計的方法,獲得艦船目標的距離-瞬時多普勒動態(tài)像。Abstract: ISAR imaging of airplane has been researched thoroughly in China. But research on ISAR imaging for ship, which is also very important in national defense, is very little. Although the difference is little in principle between airplane imaging and ship imaging, the pose variation of ship is more complicate for the fluctuation of sea, so it need to be studied specially. This paper employs Range-Instantaneous Doppler Algorithm (RIDA) based on multicompo-nent Amplitude Modulation and Linear Frequency Modulation (AM-LFM) signal parameter estimation method to obtain good ship ISAR images from real data.
