  1. Through the detailed analysis of the aaf, the defection of using chirp - fourier transform in guidance radar signal processing is pointed out

    通過對加速度模糊函數的形態分析也指明了針對線性調頻信號的二次相位匹配處理（ chirp - fourier變換）在應用到制導雷達信號處理中所存在的缺陷。
  2. The representation of aaf and its resolution not only enriches relative theory of radar signal processing and is instructive in radar parameter design and performance analysis, but also provides a practical method to quantitatively evaluate the acceleration effects on signal processing

    加速度模糊函數及其分辨力的概念不僅豐富了雷達信號理論的有關內容，為雷達參數設計和性能分析提供了一定的指導意義；而且也為實際工作中定量地衡量加速度對信號處理的影響提供了分析手段。
  3. Quick and accurate acquest of signal is critical for the utility of an lpi radar

    準確、快速的擴頻碼同步是編碼lpi雷達系統實用的前提。
  4. The realization of quick acquest under very low snr and big frequency shift is one of the key problems of lpi radar. we designed a new receiver which needs less computation spend without any decline of the performance of the radar

    如何在較低輸入信噪比和較大頻偏的條件下實現擴頻碼快速捕獲是碼同步的難點，本文在不損失系統性能的基礎上，設計了一種結構簡單的接收機實現方案。
  5. The ionosphere is a complex medium, which is aeolotropy, asymmetry, dispersive and changes randomly with time. in order to improve the communication quality of the shortwave that depends on the ionosphere, we should have aknowledge of the current condition of the ionosphere in real time. the backscatter sounding of high frequency can diagnose the real - time channel characters for shortwave communication or hf radar, which is great assistant to shortwave communication and hf radar

    地基雷達的探測空間是相對固定的，而機載預警雷達的探測范圍隨載機航線的變化而變化;由於載機和目標同時都在運動，使得某一時刻在載機探測范圍之外的目標也可能在後來的飛行過程中被探測到。
  7. The training simulator of anti - air gun fire control radar is a new kind of training equipment adapted to modern war

    摘要雷達訓練模擬器是適應現代戰爭條件而誕生的一種新型防空兵訓練設備。
  8. Assessment of radar radiant point menace in anti - air attack battle

    部分指標值未知的空中目標威脅評估模型
  9. Arsr air route surveillance radar

    航線監視雷達
  10. Air route surveillance radar

    航線監視雷達
