  1. The results of the simulations show this method can keep the amplitude of the desired signal, restrain the interference signal, and keep the output power of array to minimum

    模擬表明，採用自適應演算法能夠在保證接收方向回波信號幅度保持不變的條件下，抑制干擾信號，且使陣列輸出功率最小。
  2. The methods of direction finding mainly include maximum ( minimum ) signal method, amplitude - comparison method, phase - comparison method and time difference method

    測向的方法主要有最大（最小）信號法、比幅法、比相法、時差法。
  3. Kalman filtering just can fetch up the default, which can give the optimum estimation of signal under the condition of the minimum mean - square. and this method works in the time domain, the processing speed is fast, which make it be used in the real time signal processing

    當信號含有噪聲時， kalman濾波可以在最小均方誤差條件下給出信號的最佳估計，而且是在時域中採用第推方式進行，因此速度快，便於實時處理。
  4. Faced with the fact that there is a great deal of noise in detecting signal when using small amplitude lasting sine current on field, a developed lease minimum squares method is adopted, which makes the parameters of sine sequence with known frequency picked up on the real time. at the same time, original signal is processed by using wavelet theory, gaining true information which responses to the coating quality

    在小幅度正弦恆電流激勵檢測中，針對現場檢測信號含有大量噪聲這樣的情況，採用改進的最小二乘法，實現頻率已知的正弦序列參數的實時提取；同時利用小波理論對原始信號進行處理，得到反映塗層性能的真實信息。
  5. This paper is described wavelet transform theory, mother wavelet choice, the method to filter signal by wavelet transform and the result, prospered a way to extract feature originated from wavelet theory, which using wavelet packet analyzing method to subdivide signal both in low frequency and high frequency field, and consider energy of every layer as feature in frequency field, and in conjunction with the detailed analyzing character of wavelet packet in time - frequency plane, consider several minimum or maximum points in the lowest frequency band a s features in the time field

    本文介紹了小波變換的理論、基小波的選擇和利用小波變換進行信號濾波的方法和濾波處理結果，並提出了一種基於小波理論的新的特徵值提取方法。即利用小波包分析方法將信號在低頻、高頻段作進一步的細分，以各層分解的能量作為信號的頻域特徵值，以最低頻帶的極值點作為時域特徵值，這樣的特徵值選取方法較全面的反映了信號的時-頻特徵，優于傳統的傅里葉分析方法。
  6. One - dimension noise subspace - based method always assumes that only the minimum eigenvalue of the signal covariance matrix is the noise eigenvalue, and the corresponding eigenvector is the true noise vector and constructs the one - dimension noise subspace

    基於一維噪聲子空間方法始終認定只有信號協方差矩陣的最小特徵值才是噪聲特徵值，其對應的特徵向量才是真正的噪聲向量，並構成一維噪聲子空間。
