  1. Abstract : a new waveguide which can change the wide wall of a rectangular waveguide into a symmetric arc wall is named as a cam - rectangular waveguide. comparing to sectoral waveguide, the new waveguide has the same voltage characteristics and is easier to be produced and fixed. an approximate formula of the dominant mode fields and the normalized conductance of a longitudinal resonant slot cut in the curved wall of a cam - rectangular waveguide are given. a resonant slot linear array in c & x band is designed, in which the slot voltage distribution is equiphase and the input is matched. the input voltage stationary ware ratio and the h - plane pattern of the antenna are measured. the experimental results show the conformance with theoretical results

    文摘:把常用的矩形波導一個寬面改成圓弧形構成的波導稱為圓突-矩形波導.這種波導與扇面波導相比：電性能相當；波導管結構更加簡單，容易加工，便於安裝.文中給出圓突-矩形波導中主模場，圓曲面上縱向槽歸一化諧振電導近似公式.設計了c和x波段波導曲面縱向諧振縫隙線陣，縫隙電壓相位為同相分佈，輸入端匹配.實際測量了天線輸入端電壓駐波比和h面方向圖，理論與實驗相吻合
  2. ( 5 ) mfpic ( matched field postbeamformer interference canceller ) is proposed to cancel tow ship ' s noise. the advantage of mfpic is that it can be used to cancel the tow ship ' s noise for all arrival directions. furthermore, this new approach can be used to detect weak target, which has the same bearing angle of a strong interference

    （ 5 ）將平面波波束形成后干擾抵消與匹配場處理技術進行有機結合，探索性地提出了拖線陣聲納本艦干擾的匹配場抵消方法和匹配場處理后的干擾抵消方法，為本艦多途干擾抵消、水面強干擾抑制和水下弱目標檢測提供了新的技術途徑。
  3. Broadband source location method is investigated by using signal - phase - matching principle, and simulations and experiments are carried out to show the validity of the method ; two high resolution algorithms of broadband signals are proposed, which are the dft interpolation algorithm and the frequency invariant beam space algorithm. the proposed algorithms have no requirement for prior information of source locations, so the results of doa estimation can be unbiased ; a method of temporal - spatial averaging, which can improve the performance of doa estimation for uniform linear arrays, is given. this method can be applied in the most narrowband or broadband eigen - structure based high resolution algorithms

    提出了利用信號相位匹配法的寬帶信號方位估計方法並從模擬和實驗兩方面對其進行了驗證；提出了基於dft插值的和基於頻率不變響應波束域的兩種寬帶信號高分辨方位估計演算法，這兩種方法在進行方位估計時均不需要進行方位預估，從而避免了因角度預估可能帶來的估計偏差；最後提出了一種提高均勻線列陣方位估計性能的時空平均法，該方法可適用於多數窄帶或寬帶的特徵結構類高分辨方位估計演算法中。
