一种提高阵列处理分辨力的新算法

A New Method for Improving Resolution of Array Processing

为了改进分辨力,本文提出了一种新的阵处理方法,此法基于一种新的阵几何与空间滤波器,这种阵几何有效地增加了阵孔径,为了避免空间频率的混叠,空间滤波器能提高有效信噪比(SNR)。模拟结果表明本文方法较之现有谱估计方法有明显改进。

In this paper, a new array processing method based on a new array geometry and a spatial filter is presented. The array aperture can be increased by the array geometry. To avoid spatial frequency aliasing, spatial filtering is applied to the new array geometry as preprocessing. Also the effective signal-to-noise ratio (SNR) can be raised by the spatial filtering. Simulation results have shown much better performance achieved by using the method than that obtained by using previous methods.
