2 . a frequency extrapolation scheme is developed to effectively predict radar cross section using floating genetic algorithm based on the geometrical theory of diffraction ( gtd ) model . the threshold discrete fourier transform ( tdft ) is introduced for the data compression in angle domain 在目標散射中心建模方面,我們將浮點型遺傳算法( fga )應用于實際人工目標的gtd模型參數的抽取,利用所抽取的模型參數完成了雷達散射截面rcs的頻率擴展以及數據壓縮,并利用擴展的數據提高了距離分辨率。

Since the problem of feature extraction from 2 - d radar data can be approached as a parametric modeling and parameter estimation problem , the 2 - d type - discriminated geometric theory of diffraction based ( td - gtd ) model that discriminate between the localized and distributed scattering centers of the target is presented 在對目標散射中心的建模與參數估計中,提出采用更貼近散射機理的、特征含量更為豐富的二維散射中心模型?區分局域性與展布式散射中心類型的幾何繞射理論( td - gtd )模型。

The model is based on the theory of physical optics ( po ) , geometry theory of diffraction ( gtd ) and uniform theory of diffraction ( utd ) , and it can compute and analyze the propagation of em wave in microcellular environments by using improved ray tracing method 該模型基于物理光學( po ) 、幾何繞射理論( gtd ) 、一致性繞射理論( utd ) ,利用改進的射線跟蹤法對微蜂窩中電波傳播特性進行了數值分析計算。

The other is that the conducting body is electrically large . we can solve this case by high frequency methods or hybrid methods of high and low frequency for example the hybrid of mom and gtd 另一種情況是金屬多面體是電大尺寸,此時可以通過高頻或高低頻混合的方法來解決,例如矩量法和幾何繞射混合( mom gtd )的方法。

On top of the gds infrastructure , the administration wing , chief secretary for administration s office , provides a government telephone directory ( gtd ) website ( 通過使用政府電子目錄基建,政務司司長辦公室轄下行政署自2002年3月開始就透過互聯網提供了一個包括搜尋功能之政府電話簿網站(

All orders that will be placed are considered gtd or good till day , remaining valid only within the day and will be cancelled automatically if not executed by the end of the day 所有訂單,將列入考慮的gtd或好到一天,剩馀的有效期只有一天,將自動取消,如果不簽,由一天結束。

To estimate the td - gtd model parameters , maximum likelihood estimation ( mle ) algorithm is developed 對td - gtd模型參量的最大似然估計( mle )算法進行了推導。
