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。 -
