  • 雷達 : [訊] radar (縮自 radio detection and ranging)
  1. At last, in the circumstances of a wide - band radar is used for target detection, the length of received signal is much longer than that of the transmitted pulse signal. because the traditional matched filter collects only a small part of the energy of received signal, it is not good for detection. the generalized matched filter is obtained by improving the traditional matched filter and can collect all energy of received signal, which is good for detection

    最後,在寬帶條件下,發射信號,的目標回波的時間度要遠遠大於發射信號的時間度,傳統的匹配濾波只能收集一部分回波信號的能量,這對于檢測電磁散射比較弱的目標是不利的,而廣義匹配濾波對傳統的匹配濾波進行改進,可以將目標回波的全部能量收集起來以提高檢測性能。
