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(dá)ppi中目標(biāo)的特點(diǎn)是面積小,目標(biāo)或可能的目標(biāo)多,灰度、形狀變化無(wú)明顯規(guī)律,所以檢測(cè)和跟蹤目標(biāo)比較困難。基于雷達(dá)ppi的研究國(guó)內(nèi)外甚少,隨著高分辨率雷達(dá)和高分辨光柵顯示器的發(fā)展,基于ppi的雷達(dá)目標(biāo)檢測(cè)和跟蹤成為可能。與傳統(tǒng)的雷達(dá)目標(biāo)檢測(cè)技術(shù)相比,其潛在的優(yōu)勢(shì)在于大大增加了信號(hào)的時(shí)間積累,因此有可能提高檢測(cè)性能。
