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。基于雷達ppi的研究國內外甚少,隨著高分辨率雷達和高分辨光柵顯示器的發展,基于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,其潛在的優勢在于大大增加了信號的時間積累,因此有可能提高檢測性能。

With the widely use of raster display , pixel - level algorithm becomes a research hotspot of fundamental algorithms of computer graphics now 隨著光柵顯示器的廣泛使用,逐點算法已成為目前圖形學基礎算法中的一個研究熱點。
