摘　　要：本文提出一种新的利用单通道接收机实现方位超分辨的信号处理方法。不论是不相关信号源还是相关信号源，通过引入一系列的特定权，在不同时间间隔得到单通道接收机的一组输出功率，通过处理这组功率可以求得阵列输出的协方差矩阵。同已有的微扰法比较，所需的数据样本数减少一半，具有显著的优点。计算机模拟的结果表明该方法具有良好的效果。In this paper, we present a method of signal processing to implement super resolution direction finding with single channel receiver. In the method, we introduce a group of specific weights of array and get a group of output power measurements of the single channel receiver at different time periods. When the signals are uncorrelated or correlated, by processing the power measurements, we can recover the estimation of the array output correlation matrix. Compared with the perturbation method, the sample number of this method is reduced to half. The super resolution direction finding theory is also supported by the computer simulation results.
