Tide is the primary dynamic factor in building tidal flat ; it must be affect tidal creek system on mud flat. therefore, based on the raster image of the year of 2000, the thesis has built correlation equations between average tidal ranges and the density of tidal creeks, the ratio of the width of outlet to the length of low tidal shore, the ratio of the area of tidal creek to tidal basin respectively. the result shows that the former is high well - marked correlation ; the two latter are well - marked correlation
潮汐是塑造潮灘的主要動力因素，它必然與淤泥質潮灘上潮溝系統的發育有密切的關系，為此，本文以2000年的衛片作底圖，對潮溝系的密度、溝口寬度占低潮線長度的比值以及潮溝面積與潮盆面積的比值，分別與平均潮差建立了相關關系，結果發現，潮溝系的密度與平均潮差之間存在著高度顯著的相關性，溝口寬度占低潮線長度的比值和潮溝面積與潮盆面積的比值與平均潮差之間存在著顯著的相關性。 -

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。 -
