  1. Radio - frequency noise jamming is an effective jamming to pulse compressed ( pc ) radar. it shows the best jam quality when it ' s bandwidth equals to the jammed signal ' s bandwidth and it ' s central frequency equals to that of the jammed radar ' s receiver

    射頻噪聲干擾對脈沖壓縮雷達是一種有效干擾，在其帶寬等於雷達信號帶寬，中心頻率對準雷達的中心頻率時具有最佳的干擾品質。
  2. In the pre - procession of front radio frequency, the super - heterodyne technology which get proper a / d sampling rate through choosing a proper frequency and bandwidth is adopted

    射頻前端預處理採用成熟的超外差技術，選擇合適的中頻和帶寬，得到合適的a d采樣速率。
  3. The bottleneck of hybrid filter banks adc system is that it cannot sample directly higher radio frequency signal because of lower analog input bandwidth of its adc. in order to remove it, a kind of downsampler model based on nyquist and bandpass sampling theorem is presented, analyzed and proved in time and frequency domain, in addition a downsampler is designed according to the model. on the basis of hybrid filter banks adc system, a class of high speed hybrid filter banks adc system is proposed

    針對混合濾波器組adc系統因其adc模擬輸入帶寬低而不能對頻率較高的射頻模擬信號進行模/數轉換的瓶頸，作者提出了一種基於nyquist采樣定理和帶通采樣定理的抽取器數學模型，對該數學模型進行了時域、頻域的分析證明后，設計了一種基於該數學模型的sha抽取器，進而在混合濾波器組adc系統的基礎上，提出了高速混合濾波器組adc系統。
  4. This paper makes out the sampling frequency of bandpass sampling theorem, reduces the data rate after the sampling of broadband software radio ( signal bandwidth is 20 mhz ) and raises information processing speed

    本文確定了按帶通采樣定理采樣的頻率，降低了寬帶軟體無線電（信號帶寬為20mhz ）采樣后的數據率，提高了信息處理能力。
