提出了一种有效的超分辨谱估计方法———虚拟阵列变换法 .该方法通过对任意阵列实施变换 ,有效地增加了阵元数目 (实为虚拟阵元 ) .该方法不仅可以克服任意阵列稀布时的信号模糊问题 ,而且增加了可检测的信号源数及提高了阵列的解相干能力 .通过理论分析与仿真实验进一步证实了该方法的有效性 .
An effective method of super-resolution spectrum estimation is proposed, which is a virtual array transformation method, which effectively increases the number of array elements (in fact, a virtual array element) by performing transformation on an arbitrary array. This method can not only overcome any array The problem of signal ambiguity in the case of sparse fabric is solved and the number of signal sources that can be detected is increased and the coherence capability of the array is increased. The effectiveness of the method is further verified through theoretical analysis and simulation.
