gmti 解釋
地面動目標顯示
  1. Gmti and location based on improved esprit in distributed satellite sar

    系統中運動目標檢測定位技術
  2. We mainly discuss the methods of gmti, location, and the measure of velocity, the decrease of false alarm probability and the compensation for phase error

    主要研究mcarm數據動目標的檢測、定位和測速的方法，利用定位和測速信息進一步降低虛警概率的方法和相位誤差補償方法。
  3. The ground moving target detection ( gmti / gmtd ) is an important function of the battlefield awareness radar and fighter ' s fire - control radar. in the gmti / gmtd the ground clutter will do strong harm to the detection and stap can be used to suppress the clutter

    戰場感知雷達和機載火控雷達的地面慢速目標檢測功能也受到地雜波的制約，可以利用空時二維自適應處理提高抑制雜波的能力。
  4. Firstly, the study of real two - channel data recorded by the airborne battlefield radar is made based on the methods of gmti, which including the study of methods of two - channel equilibrium, that of the precious estimate of beam scanning angle, that of the doppler center, that of the compensation for pattern error and that of gmti and that of location of the moving target using the phase - comparison mono - pulse method

    首先，結合動目標檢測方法，對機載遠程戰場偵察雷達實驗系統錄取的雙通道數據的處理進行了研究。內容包括兩通道均衡方法研究，波束掃描角精確估計方法研究，多普勒中心估計方法研究，方向圖誤差補償方法研究，動目標的檢測和干涉定位方法研究。
  5. The using of dbs into the gmti mode of battlefield awareness radar adopting beam scanning may get the ground scene image at large area, at the same time, making gmti and marking the moving target on scene image. dbs is a kind of technique which improves the resolution of airborne radar

    把多普勒波束銳化（ dbs ）技術用於波束掃描的戰場感知雷達的地面動目標檢測模式，可以快速得到大面積的低分辨地面場景圖像，而且可同時進行地面動目標檢測，並把動目標標定到場景圖像上。
  6. This dissertation mainly discusses gmti based on real multi - channel data, which uses two or more sub - apertures

    本文主要研究動目標檢測的多通道處理方法，它利用兩個以上的子天線。
  7. These phase errors cause smearing in the image. if we can measure these errors we could find the moving target. in the preface to the article, the development of gmti technique in the field of sar are introduced briefly

    對于高分辨合成孔徑雷達（ syntheticapertureradar ， sar ） ，運動目標在其回波信號中產生額外的相位誤差，造成能量分散和圖像模糊，因此我們若能夠檢測出這個相位誤差就可以檢測到相應的運動目標。
