鑒于臺風對人類造成的巨大的危害,各國氣象部門都十分重視熱帶氣旋的預報預警工作。衛星遙感技術、雷達探測技術、數值預報技術、數值? ?統計預報技術以及計算機模擬預報技術的飛速發展和在氣象監測預報領域的廣泛應用,使人類對熱帶氣旋的監測預報水平得到了大幅度的提高。Moisture, the voids and the density of the pavement are expected for many operators in the road department. in order to promote the application of gpr to detect pavement quality as quickly as possible, in this paper some research works were zone. the mainly research results includes the following aspects : ( 1 ) since the dielectric constants of pavement medium have important influence on radar detection results, dielectric properties of pavement layers materials are analyzed for the design of practical gpr system and field application
目前探地雷達在公路上的應用還主要局限於路面結構層厚度的檢測,對路基路面物理力學指標的無損檢測被廣大公路工作者寄予厚望,這一技術的應用還有很多的工作要做,為了使其早日應用於實際,實現探地雷達對路面含水量、空隙率和壓實度的快速無損檢測,本文具體做了以下的一些工作: ( 1 )鑒于介電常數對探地雷達檢測的重要影響,對路面結構材料的介電特性進行深入分析,為路用探地雷達的實際應用測量提供理論依據。During this paper, definition of the measure enter - cover - probability is given, andthree - dimension detection space are transformed to level detection circles on differentheights. aiming at the most normal situation of symmetric line, cross - to line and cross - awayline taken by the carrier, probablely - enter - cover - target - distribution are analysed in relativemovement method on the premise that targets fly perpendicular to the flying direction of thecarrier. mont - cario method is used to simulate uniformly - distributed - targets situation and getthe measure, and results are used to analyse the influence of line - landscape - orientation - ratio, line - portrait - ratio, and speed - ratio on the measure. for further research, influences of height and blind space are also discussed on base ofradar level detection range, and situations of non - uniformly - distributed targets are alsoresearched
為了分析主動探測空間動態性能,本文首先提出以「目標進入雷達覆蓋區概率」 (簡稱為「覆蓋率」 )作為評價指標;然後將三維探測空間轉換為不同高度層對應的水平探測圓,針對載機採用雙平行航線、交叉相向航線和交叉同向航線的最一般情形,採用相對運動的方法,分析目標垂直入侵時可能進入雷達覆蓋區的目標分佈情況;再運用蒙特卡洛法進行模擬計算,分析並比較目標服從均勻分佈時航線橫比、航線縱比及速度比對性能的影響。分享友人
