-
The computational results of the particle images are agreement with the simulated datain reasonable, the most absolute difference of the displacement is 0. 6671 pixel at the x abscissa and 0. 7928 pixel at y abscissa ; the computational results are equal to the data form the algorithm of particle brightness - distribution pattern tracking ( the conventional cross - correlation algorithm ) at voluminous points, their discrepancy is only one pixel at few points, mostly in boundary area
西安理工大學碩士學位論文最後，在visualfortran環境下給出了這種演算法的具體實現，處理模擬粒子圖像的結果與模擬數據比較吻合，最大位移絕對誤差在x方向是0 . 6671像素，在y方向是0 . 7928像素;計算結果與示蹤粒子灰度分佈模板法（基本的互相關法）在絕大部分點是相同的，只在少數點相差一個像素，而且大多出現在邊界區域。 -
It is shown that the proposed scheme guarantees the stability of the closed - loop system and achieves tracking performance idex, meanwhile the influences of external disturbance, neural network approximation error and the cross - coupling of input to output on the tracking error are reduced to a prescribed level
該方法不僅保證了閉環系統的穩定，而且使外部干擾、神經網路逼近誤差及輸入對輸出的交叉耦合對跟蹤誤差的影響衰減到給定的水平。 -
The implement of direction finding cross location and errors analysis are on the focus. the multi - warships bearings - only tracking algorithm based on direction finding cross location and distributed multi - warships bearings - only tracking are also presented. ( 6 ) the observation prerequisite of single warship bearings - only tracking is analyzed, and optimal maneuver of the observer warship is discussed
5研究了多艦純方位跟蹤的演算法，把多艦純方位跟蹤分成集中式跟蹤和分散式跟蹤兩類，並分別進行了分析比較，重點研究了測向交叉定位法的實現及誤差分析，給出了基於測向交叉定位的多艦對運動輻射源的跟蹤演算法和基於信息融合的多艦純方位分散式跟蹤演算法。 -
In the process of tracking, when the objects rest disappear cross, or the new objects appear between the frames in the dynamic image, the algorithm can solve it correctly to realize the proper tracking of the multi - object, what ' s more, it correctly judges whether dynamic objects wander in the tracking areas, which ensures the validity of the counting
在跟蹤過程中考慮了目標暫時靜止、消失、交叉多種情況，並對動態圖像中幀間出現新目標進行了正確處理，實現了多目標的正確的跟蹤，進而對運動目標是否在跟蹤區域徘徊進行判斷，保證了進出目標計數的正確性。 -
But it is not suitable for online implementation or for tracking signal components with characteristic that change with time, a new modified algorithm is present based on the adaptive short - time kernel. simulations show that adaptive short - time kernel time - frequency distribution has better performance than anyother time - frequency distribution not only in the time - frequency resolution but also in the cross - components suppression
通過對模擬信號計算其自適應短時高斯核時頻分佈，模擬結果表明，無論從改善信號的時頻解析度還是抑制交叉項方面，自適應短時核時頻分佈均表現出了較好的特性。 -
The algorithm of cross product automatic frequency control ( cpafc ) and frequency bin technology is used for tracking larger frequency deviation. the paper gives out a scheme of digitized carrier synchronization loop, in which the digitized costas loop is used as a basic part while cpafc and frequency bin technology as auxiliary
在此基礎上提出了數字化、軟體化的載波同步環路演算法方案，主要採用數字化科斯塔斯環的形式，並加以自動頻率跟蹤演算法和頻率開槽技術的輔助來實現載波同步。
