商品描述
Based on a detailed analysis of the signal model of the moving target, this thesis focuses on the theories and applications of ground moving target indicator (GMTI) and ground moving target imaging (GMTIm) algorithms in synthetic aperture radar/ ground moving target indicator (SAR/GMTI mode), wide-area surveillance ground moving target indication (WAS-GMTI) mode and frequency modulated continuous wave synthetic aperture radar (FMCW SAR) systems. The proposed algorithms can not only indicate and image fast-moving targets, but are also effective in the context of slow-moving target processing. The system design scheme combines the mechanical scanning mode and the airborne SAR system, while the azimuth moving target indication algorithm employs the additional range walk migration induced by FMCW SAR systems. In addition, the non-ideal errors that deteriorate the performance of GMTIm algorithms in real SAR data processing are discussed, and suitable compensation methods are provided.>
商品描述(中文翻譯)
根據對移動目標信號模型的詳細分析,本論文專注於地面移動目標指示器(Ground Moving Target Indicator, GMTI)和地面移動目標成像(Ground Moving Target Imaging, GMTIm)算法在合成孔徑雷達/地面移動目標指示器(SAR/GMTI模式)、廣域監視地面移動目標指示(Wide-Area Surveillance Ground Moving Target Indication, WAS-GMTI)模式以及頻率調變連續波合成孔徑雷達(Frequency Modulated Continuous Wave Synthetic Aperture Radar, FMCW SAR)系統中的理論與應用。所提出的算法不僅能夠指示和成像快速移動的目標,還能有效處理慢速移動目標的情境。系統設計方案結合了機械掃描模式和機載SAR系統,而方位移動目標指示算法則利用FMCW SAR系統引起的額外距離走移遷移。此外,論文還討論了在實際SAR數據處理中,影響GMTIm算法性能的非理想誤差,並提供了適當的補償方法。
