  1. Targets in the radar ppi have the main property of the little area, a few targets and irregular change of grey. so it is difficulty to detect and track the target. the study of the radar ppi is very few inland and abroad. with the development and implement of high resolution radar and high resolution raster display, target _ tracking and detecitng based on the radar ppi will be feasible. it ' s great excellence is to increase time accumulation compare with the detecting techenicial of the traditional radar

    雷達ppi中目標的特點是面積小，目標或可能的目標多，灰度、形狀變化無明顯規律，所以檢測和跟蹤目標比較困難。基於雷達ppi的研究國內外甚少，隨著高解析度雷達和高分辨光柵顯示器的發展，基於ppi的雷達目標檢測和跟蹤成為可能。與傳統的雷達目標檢測技術相比，其潛在的優勢在於大大增加了信號的時間積累，因此有可能提高檢測性能。
  2. Radar altimeter is a kind of very important microwave sensing instrument for observing the earth, and there are a lot of key technologies involved in the high resolution spaceborne radar altimeter ( hrsbralt ). the principle of hrsbralt, the acquisition and track methods, the if simulation, the closed loop internal calibration method, the pulse repeat frequency ( prf ) design, and the ocean - land compatible altimeter design are studied in this dissertation

    雷達高度計是一種重要的微波遙感儀器，本文就高解析度星載雷達高度計的工作機理、跟蹤方法、大時帶積在軌閉環內校準以及海陸兼容等內容進行了深入的研究，具體包括以下八個方面的內容： （ 1 ）深入研究了星載雷達高度計的工作機理，並對典型雷達高度計系統進行了分析。
  3. Very high resolution radar

    甚高分辨力雷達
  4. The study of the polarimetric man - made targets detection algorithms is very useful for improving the application of sar. polsar can create high - resolution images. because of the wide and latent applications of polsar in many areas of military, civil and scientific researches, polsar is one of the most active fields in radar and remote sensing nowadays

    在此背景下，開展關于polsar的圖像目標檢測以及目標分類等方面的研究，對于解決如何優化polsar系統應用，提高對polsar圖像的解譯能力，推動我國polsar系統走向應用，具有重要的理論和實際意義。
  5. Synthetic aperture radar ( sar ), as a high resolution microwave instrument, has an important status in the remote sensing. it has ability of large planetary image areas in all weather during day and night and has ability of penetrating, these characteristics make it very important in applied aspect

    合成孔徑雷達（ sar ）是一種高解析度的微波遙感設備，在遙感成像領域有著舉足輕重的地位，它具有全天時、全天候、大面積成像的工作能力，並對地物有一定的穿透能力，這些特點使它在應用方面具有極端的重要性。
  6. Spotlight synthetic aperture radar can efficiently obtain an image with very high azimuth resolution, since its antenna illuminate the fixed target on the ground. bistatic radar is not a new concept and its fundamental principles have been known and demonstrated many years before the development of operational monostatic radar

    由於其天線波束始終照射同一目標場景，因此可獲得更大的方位多普勒帶寬和更高的方位分辨力，但實際上由於受數據處理條件、載體運動誤差等因素的影響，方位解析度的提高是有限的。
  7. The demand of autofocus for high resolution real time synthetic aperture radar ( sar ) is very high

    摘要高解析度機載合成孔徑雷達實時成像對自聚焦的要求非常高。
