  1. The master dissertation introduces passive correlative orientation system and base theory in signal dispose briefly in the first place. the system takes tv sound fm signal from tv satation signal. the power rate of tv station signal to sound signal is ten to one. in the case of submerged by mussy weave and machine ' s hot noise, dispersed target signal is feeble

    系統採用臺的視伴音調頻信號,其中臺信號與伴音信號功率之比基本為10 : 1 ,並且目標散射信號較弱,一般情況下淹沒在雜波和機器熱噪之下,採用常規的脈沖檢很難對遠離的目標進行檢,而以臺直達信號作為參考與目標回波信號進行相關檢;系統中信號的相關處理會產生旁瓣,而強目標的旁瓣會影響附近的弱目標檢
  2. The system is based on ultrasonic multiple pulse - echo principle, the control circuit of sonic circulation, can improve the precision of measurement by extending the time of detection

    本系統以超波多次脈沖反射原理為基礎,設計循環反射控制路,達到以延長量時間為代價提高量精度的目的。
  3. In cellular envirorunents, because of the influence of several adverse factors, such as muitipath, non - line - of sight propagation, noise, interference and channel frequency characteristics, radio statistics measuremenis like tdoa, toa and aoa related to mobile position, the performance of location algorithms mny be significantly degraded and the position estimation of ms is inevitably biased

    在蜂窩網路環境中,由於受多徑、非視傳播、噪、干擾和通道頻率特性等多種不利因素的綜合影響,使tdoa 、 toa 、 aoa等與移動臺位置有關的波特徵量值不可避免地出現較大誤差,從而使各種定位演算的性能顯著下降,造成移動臺位置估計出現較大偏差。
