  1. The problem of doa ' s estimation of multiple source signals incident on a arbitrary array in the presence of both unknown spatially correlated noise and sensor errors is firstly considered. a modified ml estimation of doa ' s and sensor gain errors is presented. unlike previous work, the proposed method does not impose any structure constraints or parameterization of the signal and noise covariances. the algorithm can be carried out via the alternating projection approach. finally, the performance of the proposed method is shown with computer simulations as well as real array data

    在空間相關色噪聲環境及存在誤差情況下,首先給出了基於最大似然的doa及幅相誤差聯合估計演算法,該演算法對信號和噪聲無任何約束,且適用於任意結構。演算法可以利用交替投影搜索實現,計算機擬實驗和外場實測數據表明,本章演算法能給出比傳統的最大似然方法更高的估計性能。
  2. Abstract : in this paper, a variety of encryption methods for optical image security are comparatively studied. according to the different method, the encrypted image can be transformed into white or color noise. the encryption phase can be the random phase or the chaotic sequence as well as the calculated result by used of the phase retrieval algorithm. the image quality and the correlative recognition ability of decrypted image are affected by the different part of the decryption phase and the amount of high frequency or low frequency used in the process of decryption

    文摘:本文分析比較了多種實現光學圖象相位加密的方法,發現不同方法獲得的加密圖象有不同類的噪音分佈.無論加密相位是隨機相位板、渾沌序的相位,還是用相位重構演算法計算的結果,它們都能起到加密圖象的功能.解密圖象的質量或被相關識別的能力與解密過程中所使用正確解密相位的不同部分以及高低頻分量多少有關,且其依賴程度是由不同的加密方法自身決定
