    本文主要進行雷達波形設計研究以及研究小波理論在超寬帶雷達中的應用，集中體現在以下幾個方面：一類新的組合雷達波形設計及壓縮脈沖時間旁瓣抑制技術研究、超寬帶雷達多通道數據採集方法中前端射頻接收部分的設計及研製、基於小波（包）方法的時延估計方法。
  3. The methods of measurement for monotone and dual tone intermodulation suppression are provided as receiver works at fh mode based on intercept probability and false alarm probability are up to par

    提出在滿足截獲概率和虛警概率條件下，接收機跳頻工作方式的單音和雙音互調抑制性能測試方法。
  4. According to the ideology of software radio theory, the realization of intermediate frequency ( if ) digitalized direct sequence spread spectrum ( dsss ) receiver is one of the focuses in dsss communications study. it is of great value to deploy narrowband interference ( nbi ) suppression techniques in if digitalized dsss receiver for commercial and military applications

    根據中頻數字化這一軟體無線電思想實現擴頻接收機是目前擴頻通信研究的熱點，在中頻數字化擴頻接收機體系結構內研究窄帶干擾抑制技術具有重要的商業和軍事應用價值。
  5. Multi - tone interference suppression spread spectrum receiver in wavelet domain

    小波域抑制多音干擾的擴頻接收機
  6. Over multiple - path fading channel, a novel iterative single - tone interference suppression scheme is proposed for convolutionally coded system in the single - tone interference environment. the iterative receiver is based on the combination of iterative single carrier frequency domain equalization and interference rebuilding and cancellation

    該方法利用衰落通道下單音信號的頻域特性，對干擾信號進行重建及干擾抵消，同時，結合單載波頻域均衡迭代檢測技術，實現衰落通道中的聯合單音干擾抑制及信號檢測。
  7. Most of the lectures on nbi suppression assume that the spread spectrum signal and the background noise are white. this assumption cannot stand up in digitalized receiver because of the if oversampling and digital low pass filtering in digitalized receiver. the code - aided optimal filtering is studied extensively in the circumstance of oversampling and colored background noise

    以往的擴頻抗干擾文獻多將擴頻信號和背景熱噪聲假設為白噪聲，由於在數字正交解擴解調中採用過采樣和數字低通濾波，這一假設在數字化擴頻接收機中並不成立。
