  1. Some valuable conclusions are summarized by theoretical analysis and simulation experiments : from the side of signal processing, pulse jamming can be deleted by the method of time - domain sliding window accumulation and can be restored by interpolative prediction. ; gauss white nose can be attenuated while jamming disperse point - target by the method of time - frequency analysis in time - frequency domain. ; radio frequency noise jamming can be deleted by the method of average range frequency spectrum and notching in frequency domain

    通過大量的理論分析和模擬實驗,得到了一批具有一定價值的結論:從信號處理的角度出發,對于脈沖式干擾,能夠運用時域滑動窗口積累的方去掉,並且通過預測值得到較好的恢復;對于高斯白噪聲干擾,在時頻變換域應用時頻分析方可減小其對分散點目標的干擾;對于射頻噪聲,通過平均距離頻頻和頻域陷波的方可以去掉;從改變合成孔徑雷達系統角度出發,類雙基地雷達能夠避免各種干擾,對發射信號進行調幅,調以及改變調頻斜率都是較好的抗干擾方
  2. From 1920s up to now, various techniques and methods for wave field decomposition, propagation and migration / imaging have been well developed, such as the kirchhoff asymptotic method, frequency - wavenumber domain phase - shift and phase - shift - plus - interpolation methods, and the one - way wave equation based phase - screen and generalized screen methods, etc. wave field extrapolation in these methods is implemented based on the expansion of the wave field by sets of basic functions like spatial fourier harmonies, modes, and green ' s functions

    自上個世紀二十年代至今,波場分解、傳播與偏移成像技術經歷了將近一個世紀的發展,形成了多種不同的方,如kirchhoff波動方程高頻近解方,頻率-波數域的移( phase - shift )方移-( pspi )方,以及在混合域中基於單向波動方程的位屏、廣義屏方等。
  3. To obtain the fast matrix - vector multiplication algorithm, we approximate the kernel function with piece - wise polynomial and get the approximate coefficient matrix a using the approximate kernel function. let n be the number of quadrature points and k2 be the number of interpolating knots at each subdomain. it is proved that the construction of a and the matrix - vector multiplication ax require o ( nk ) operations respectively

    我們利用對核函數進行分片多項式值逼近得到適用於快速方的近系數矩陣a :矩陣a的計算和矩陣-向量乘ax各需要o ( nk )次運算,存貯a需要佔用o ( nk )存,其中n為積分節點的個數, k ~ 2為每個小區域的值節點數。
