  1. The potential applications of amr include both civil and military communication, especially non - cooperative communications and communication confrontation, such as identifying signals, supervising signals, distinguishing interference, electronic confrontation, analyzing military threat, etc. on the basis of our analysis to the existing research on feature abstraction, the related feature abstraction methods are optimized in this paper, resulting several effective methods such as the feature abstraction based on transformation domain, stepped voltage level analysis, normalized carrier - free spectral energy analysis, squared signal and fourth powered signal analysis, etc. both the decision theory based on recognition algorithms and the artificial neural network ( ann ) based on recognition algorithms is analyzed, and the former is selected as it is more appropriate for this research

    調制類型的自動識別廣泛應用於民用通信與軍用通信,尤其是對于非合作性通信、通信對抗,比如:信號確認、信號監控、辨識、子對抗、軟體無線子救援、通信對抗、軍事威脅分析等。本論文在分析現有研究的基礎上,借鑒了已有的特徵提取方法,對相關調制類型特徵提取方法進行了優化,使用了一些有效的方法,如基於變換域特徵提取方法、梯層分析方法、剔除后的歸一化頻域能量分析方法、信號方后的頻譜分析方法、信號四次方后的頻譜分析方法等。通過對基於決策理論和基於人工神經網路兩種識別演算法進行分析,本論文選擇了較適合的基於決策理論的識別演算法。
  2. We analyzed the anti - jam and band inside anti - interfere performance of the system, and the low probability intercept ( lpi ) of the traditional direct sequence spread spectrum ( dsss ) modulations in the uav platform ' s applications. so a new modulation technique using a multi - level pseudo noise ( pn ) code has been presented. the new multi - level pn code is built from a high speed pn code through a low passed filter ( lpf )

    分析了系統抗阻塞式和抗帶內頻帶的性能,以及常規bpsk qpsk - dsss調制在無人機通信中存在的安全隱患,提出了一種用多pn碼進行擴頻調制的方法:採用高速pn碼,經過低通濾器,產生多pn碼進行直序擴頻調制,能在低信噪比情況下有效抵抗方率檢測器對系統的檢測。
  3. The sidelobes are controlled by introducing a large number of interfering signal at many angles throughout the sidelobe region
